Answer:
The width of the rectangle is 7 units
Step-by-step explanation:
Here, we want to find the width of the rectangle
Mathematically, the area of the triangle is length * width
(2x + 1)(2x-1) = 35
4x^2 - 1 = 35
4x^2 = 36
x^2 = 9
x = 3
Substituting 3 in 2x + 1
we have 2(3) + 1 = 6 + 1 = 7 units

Which inequality represents all the solutions of -2(3x + 6) ≥ 4(x + 7)?
A. x ≥ -4
B. x ≤ -4
C. x ≥ 8
D. x ≤ 8
Answer is B: x≤-4
Step-by-step explanation:
-2(3x+6)≥4(x+7)
distribute
-6x-12≥4x+28
add 12 on both sides and subtract 4x on both sides
-10x≥40
divide by -10 on both sides. keep in mind that this flips the inequality sign.

What is the Greatest Common Factor of the two monomials?
15a²b, 35ab2
Answer:
5ab
Step-by-step explanation:
To find the greatest common factor (GCF), you will need to find the largest value that both of these monomials can be divided by. There are three different parts to these monomials: the number value, variable a, and variable b.
Find the largest number of each element that can be divided by both.
Numbers: the GCF of 15 and 35 is 5 (15/5 = 3, 35/5 = 7, 3 and 7 are prime numbers and therefore, cannot be divided further)
Variable a: the GCF of a² and a is a
Variable b: the GCF of b and b² is b
Therefore, the GCF is 5ab.

5. Suppose Sal’s total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different
Answer:
Given:
Profit of every sandwich = $2
Profit of every wrap = $3
x = sandwich
y = wrap
Last month: 2x + 3y = 1,470
Next month: 2x + 3y = 1,593
Based on the given equation:
Both still have the same profit. $2 for sandwiches and $3 for wraps.
The only reason why there is a difference in the total amount is the change in the number of sandwich or wrap sold in a given month.
Since, next month's total sale is higher than last month's total sale, it is safe to assume that the sale of sandwich or wrap is higher than last month's sale.
The graph of the functions for the two moths are similar because both conditions have same slope and they are different because they have different [tex]y-[/tex] intercept.
What is slope intercept form?
The graph of the linear equation is a line with [tex]m[/tex] as slope, [tex]m[/tex] and [tex]b[/tex] as the [tex]y-[/tex] intercept. This form of the linear equation is called the slope-intercept form, and the values of [tex]m[/tex] and [tex]b[/tex] are real numbers.
It is given that, the profit amount is [tex]$\$2$[/tex] for each sandwich and [tex]$\$3$[/tex] for each wrap and total profit is [tex]$\$1593$[/tex].
So, the equation is,
[tex]2x+3y=1593[/tex]
Change the equation in slope intercept form [tex]y=mx+b[/tex]
So,
[tex]2x+3y=1593[/tex]
Subtract [tex]2x[/tex] in both sides.
[tex]2x+3y-2x=1593-2x[/tex]
[tex]3y=1593-2x[/tex]
Divide each side by [tex]3[/tex].
[tex]$\frac{3y}{3}=\frac{1593}{3} -\frac{2x}{3}[/tex]
[tex]$\therefore y=-\frac{2x}{3}+531$[/tex]
So, the equation is,
[tex]y=-\frac{2x}{3}+531$[/tex]
The graph of the equation is shown below.
From the below graph, we will have two step down and three step right.
So, slope looks like rise over run.
So, the graphs represents, how many wraps and sandwiches were sold.
Both will have same slope, because if we will make the equation for this, it is like,
[tex]$2x+3y=1593$[/tex]
The calculation is follow for both condition is same.
Since, both conditions have same slope but different [tex]y-[/tex] intercept.
Hence, next month's total sale is greater than last month's total sale, it is safe to consider that the sale of sandwich or wrap is greater than last month's sale.

If so, in which step?
Given:
The expression is

To find:
The Natalie's mistake.
Solution:
We have,
[tex]\left( 4^{-3} \cdot 2^{-3} \right)^{0} [/tex]
Using properties of exponents, we get
[tex]=\left( (4\times 2)^{-3} \right)^{0} [/tex] [tex][\because a^mb^m=(ab)^m][/tex]
[tex]=\left( (8)^{-3} \right)^{0}[/tex]
[tex]=\left( 8 \right)^{0}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]=1[/tex] [tex][\because a^0=1,\text{ where, a is any non zero number}][/tex]

Please mark brainliest Hope this helps :D
The value of the given expression 5² + 2³ is 33
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
The given expression, 5² + 2³, involves two operations: squaring and cubing.
The first operation, 5², means that we need to multiply 5 by itself, which results in 25.
The second operation, 2³, means that we need to multiply 2 by itself three times, which results in 8.
Therefore, 5² + 2³ is equivalent to 25 + 8, which gives us 33 as the final answer.
In other words, the value of the given expression is 33. This calculation involves basic arithmetic operations and can be easily solved using a calculator or mental math skills.

Susan has 3/4 cup of raisins and she divides them into 3/8 cup servings. How many servings are there in 3/4 cup of raisins?
2 cups raisins
Step-by-step explanation:
3/4 divided by 3/8
3/4 x 8/3 = 2/1 = 2
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
There are two 3/8 cup servings in 3/4 cups of raisins.
The number of 3/8 cups of servings = 2 servings.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Number of cups of raisins Susan have = 3/4 cups
The number of 3/8 servings in 3/4 cups of raisins:
= 3/4 ÷ 3/8
= 3/4 x 8/3
= (3 x 8) / (4 x 3)
= 2 servings
Thus,
There are two 3/8 cup servings in 3/4 cups of raisins.
The number of 3/8 cups of servings = 2 servings.

A high school championship football game was attended by 1580 fans. there were 640 were out of state fans at the game. the other fans were local.
Answer:
Step-by-step explanation:
1580-640=940 were local
No. of local fans = 940
What is subtraction?Subtraction is one of the four basic arithmetic operations in mathematics. It represents the operation of removing objects from a collection. The minus sign signifies subtraction −.
Example: There are nine oranges arranged as a stack, out of which four oranges are transferred to a basket, then there will be, 9 – 4 oranges left in the stack, i.e. five oranges.
Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5.
Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers such as negative numbers, fractions, rational & irrational numbers, decimals, functions, matrices and vectors.
Given,
Total fans attended championship = 1580
No. of out of state fans = 640
No of local fans = total fans - no. of out of state fans
= 1580 - 640
No of local fans = 940
Hence, there were 940 local fans who attended football championship.
