Quotient = Dividend ÷ Divisor
Let the number the represented by X
Hence:
The expression that represents "five less than the quotient of a number and three"
Is X ÷ 3 = Quotient - 5
Therefore, the two operations are needed to write the expression is Division and Subtraction

Dude I am so sorry but I'm just as confused as you are-
Answer:
36 in.
Step-by-step explanation:
the perimeter of the square is 4s and the perimeter of the triangle is 3(s+3).
since the perimeters are the same you can set them equal to each other and solve.
you should get s=9
substitute 9 into the square perimeter equation to get 36 in.
When the expression x^2 + bx - 24 is factored completely, the difference of the factors is 11. Find both factors if it is known that b is negative.
write the steps on the paper pleaseeee
i need it asap
Answer:
The two factors are (x + 3) and (x - 8)
Step-by-step explanation:
The given function is x² + b·x - 24
The difference between the factors = 11
The sign of coefficient b = Negative
Therefore, we have;
The factors as (x - c) and (x + d)
-b = d - c...(1)
d × (-c) = -24...(2)
(x + d) - (x - c) = 11
Which gives;
x + d - x + c = 11
∴ d + c = 11...(3)
From equation (3), we have;
d = -24(-c) = 24/c
d = 24/c
Substituting the value of d in equation (3) gives;
d + c = 24/c + c = 11
24/c + c = 11
∴ c² + 24 = 11·c
c² + 24 - 11·c = 0
c² - 11·c + 24 = 0
(c - 8)·(c - 3) = 0
c = 8 or 3
From d + c = 11, we have, d = 3 or 8
Given that -b = d - c, therefore c > d and c = 8, d = 3
Therefore, the two factors are (x - 8) and (x + 3).
how do you get that answer

Match each polynomial to its factored form.
x^2+8x +16
x^3-64
x^2-16
(x-4)(x^2+4x+16)
(x+4)^2
(x-4)(x+4)
Answer:
x^2+8x +16 >> (x+4)^2
x^3-64 >> (x-4)(x^2+4x+16)
x^2-16 >> (x-4)(x+4)
Step-by-step explanation:
Each polynomial is matched to its factored form. These are the correct answers. I did this on EDGE!
Polynomial is an expression that consists of indeterminates(variable) and coefficients.
What are polynomials?
Polynomial is an expression that consists of indeterminates(variable) and coefficients, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
To know which polynomial to match, solve the factors.
A.) (x-4)(x²+4x+16)
[tex](x-4)(x^2+4x+16)\\\\=x(x^2+4x+16)-4(x^2+4x+16)\\\\= x^3 + 4x^2 + 16x - 4x^2-16x-64\\\\=x^3 -64[/tex]
Hence, (x-4)(x²+4x+16) will match x³-64.
B.) (x+4)²
[tex](x+4)^2\\\\= x^2+8x+16\\[/tex]
Hence, (x+4)² will match x²+8x+16.
C.) (x-4)(x+4)
[tex](x-4)(x+4)\\\\ = x^2-16[/tex]
Hence, (x-4)(x+4) will match x²-16.

A girl's club held a fundraiser last year and raised $600 for the local soup kitchen. This year they raised $960. What is the percent change in the total amount raised by the girl's club? The percent change is 0.38%. The percent change is 0.6%. The percent change is 38%. The percent change is 60%.
Answer:
The percent change is 60%.
Step-by-step explanation:
given that the old amount is
$600
also the new amount is $960
the change is 960-600= $360
therefore the expression for percent change is given as
%change= new-old/old
%change= final-initial/initial
%change= 960-360/360
%change= 360/600
%change= 0.6
0.6*100
=60%
The percent change is 60%.

Write the equation, in slope intercept form, for the line shown in the graph below.
Answer:
y = -2x + 3
Step-by-step explanation:
The slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
those are the only things you need to find when doing slop-intercept form.
Slope: Find 2 points on the line
ex. (0,3) ; (3, -3) I just chose ones that were not decimals
To find slope you need to do this : y - y / x - x
you can chose any order, as long as the pairs are together, either first or second.
3 - (-3) / 0 - 3 is one way
6 / -3 is the slope
-3 - 3 / 3 - 0 is another
-6 / 3 is the slope
They are essentially the same.
you can simplify them to get -2
Y-Intercept:
this is really easy, just find where the line touches the y-axis
y-intercept = (0,3)
We have: slope = -2
y-intercept = 3
Now, replace the m and b in the equation-
y = -2x + 3

Find three consecutive even integers such that the sum of twice the smallest number and three times the largest is 42.
Answer:
The three consecutive even integers are 6, 8, 10
Step-by-step explanation:
The difference between each two consecutive even numbers is 2Assume that the first number is x, then the other two numbers are x + 2 and x + 4∵ The three consecutive even numbers are x, x + 2, x + 4
∵ The smallest number is x
∴ Twice the smallest number = 2x ⇒ (1)
∵ The largest number is x + 4
∴ Three times the largest number = 3(x + 4) = 3(x) + 3(4)
∴ Three times the largest number = 3x + 12 ⇒ (2)
∵ The sum of twice the smallest number and three times the largest is 42
→ Add (1), (2) and equate the sum by 42
∴ 2x + 3x + 12 = 42
→ Add the like terms
∴ 5x + 12 = 42
→ Subtract 12 from both sides
∴ 5x + 12 - 12 = 42 - 12
∴ 5x = 30
→ Divide both sides by 5
∵ [tex]\frac{5x}{5}=\frac{30}{5}[/tex]
∴ x = 6
∴ The smallest integer is 6
∴ The middle integer is 6 + 2 = 8
∴ The largest integer is 6 + 4 = 10
∴ The three consecutive even integers are 6, 8, 10

Fun Station is having a sale. Video games are 20% off, board games are 50% off, and basketballs are $12. Let v represent the original price of a video game. Let b represent the original price of a board game. Write an equation to find the total sale price of 2 video games, 3 board games, and 1 basketball.
Answer:
y=1.6v+1.5b+12Step-by-step explanation:
Let v represent the original price of a video game.
Let b represent the original price of a board game.
let y be the total
y=v+b+12
Video games are 20% = 100-20= 80%= 0.8v
board games are 50% =100-50=50%= 0.5b
the total is now
y=0.8v+0.5b+12
the expression for the total sale price of 2 video games, 3 board games, and 1 basketball
y=2(0.8v)+3(0.5b)+12
y=1.6v+1.5b+12

What are complementary angles?Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).
From the diagram,
1) ∠GNH+∠HNJ=90°
So, ∠GNH and ∠HNJ are complementary angles
2) ∠JNK+∠KNL≠180°
∠JNK and ∠KNL are not supplementary angles
3) ∠KNL+∠LNM=90°
So, ∠GNH and ∠HNJ are complementary angles
4) m∠HNK+m∠KNL=180°
∠HNK and ∠KNL are supplementary angles
5) m∠MNG+m∠GNH=90°
So, ∠MNG and ∠GNH are not complementary angles
Therefore, options 1, 3 and 4 are correct.
