Answer:
48=2(x+4)+2x
Step-by-step explanation:
Step one:
given data
Perimeter= 48ft
let the with be x
length= x+4
Step two:
the expression for the perimeter is
P=2L+2W
substituting
48=2(x+4)+2x
48=2x+8+2x
solve for x
48=4x+8
48-8=4x
40=4x
x=40/4
x=10ft
Step three:
the width is 10 ft
the lenght= x+10
length= 10+10= 20ft
If using the method of completing the square to solve the quadratic equation

wrtie an equation in slope-intercept form for the line that passes through the point (1,-1) and is parallel to the line whose equation is y= 2x+5
Answer:
y = 2x - 3
Step-by-step explanation:
Since the line needs to be parallel, you can take the slope of the other equation and input it into y = mx + b:
y = 2x + b
Next, to have it intercept at the given coordinates, input the coordinates into the equation and solve for b:
-1 = 2 ( 1 ) + b
-1 = 2 + b
-1 - 2 = b
-3 = b
Now input the "b" value into the equation and you have the answer:
y = 2x - 3

Answer: 10x+14
Step-by-step explanation: In a equation like this one you just add like terms. So 10 and 4 are added and make 14. Since there are no like terms for 10x then you just leave it be.
Mr. Gatti is looking to buy some apples to bake a fresh & tasty apple pie. He goes to the store and sees two deals that are going on for apples: Deal A - 3/4 of a pound for $2.50 Deal B - LaTeX: 2\frac{2}{10}2 2 10 pounds for $5.25 1. Which is the better deal, and why? Explain your answer. Put your answer in $ per pound format
Answer:
Deal A is best
Step-by-step explanation:
Given
Deal A:
3/4 lb for $2.50
Deal B:
2/10 lb for $5.25
Required
Which deal is the better
To do this, we simply calculate the lb/dollar ratio
i.e.
[tex]Ratio = \frac{Amount}{Size}[/tex]
For Deal A:
[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]
[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]
[tex]Ratio = \frac{\$10}{3}lb[/tex]
[tex]Ratio = \$3.33/lb[/tex]
For Deal B:
[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]
[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]
[tex]Ratio = \frac{52.5}{2}lb[/tex]
[tex]Ratio = \$26.25/lb[/tex]
The better deal is the least expensive:
Hence: Deal A is better

What theorem is used to determine if the base angles of a triangle are congruent?
Answer:
Isosceles Triangle Theorem
Step-by-step explanation:
An isosceles triangle is a tringle that has a pair of congruent sides and a pair of congruent angles. If the triangle has two congruent angles its isosceles. So therefore, you would use the Isosceles Triangle Theorem.
The Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.
What is base angles of triangle?"The angles that have the base as one of the side of triangle. "
What is isosceles triangle?"It is a triangle that has any two sides equal in length and angles opposite to equal sides are equal in measure."
For given question,
We need to find the theorem that is used to determine if the base angles of a triangle are congruent.
We know that the Isosceles triangle theorem states that 'If two sides of a triangle are congruent, then angles opposite those sides are congruent.'
In isosceles triangle any two sides of the triangle are equal in length.
If we draw the angle bisector for an angle between two equal sides, then we get two triangles.
Then by SAS congruence postulates we can prove that both the triangles are congruent and so the base angles of a triangle are congruent.
Therefore, an Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.

Ella and some friends are going to a movie. Each movie ticket costs $5.
Create an equation that shows the relationship between how many friends, n, attend the movie and the total cost in
dollars, c.
Answer: c = 5n
Step-by-step explanation:
Cost of movie ticket = $5 per person
Number of people attending the movie = n
The total cost c, will be the multiplication of the cost of movie ticket per person by the total.number of people attending the movie. This will be:
c = 5 × n
c = 5n

slope=−4/3, y-intercept = 3
Answer:
The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
Step-by-step explanation:
The form of the equation is y = m x + b, where
m is the slopeb is the y-intercept∵ The slope of the line is [tex]-\frac{4}{3}[/tex]
∴ m = [tex]-\frac{4}{3}[/tex]
→ Substitute it in the form of the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + b
∵ The y-intercept = 3
∴ b = 3
→ Substitute it in the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + 3
∴ The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
A combination lock is opened with the correct sequence of three numbers between 0 and 49 inclusive. If a number can be used more than once, what is the probability of guessing those three numbers and opening the lock with the first try? (Write answer as a simplified fraction
Answer:
125,000
Step-by-step explanation:
Given that :
Sequence of three numbers chosen from 0 to 49 inclusive
Since numbers can be repeated ; hence numbers do not have to be different ;
Number of digits between (0 - 49 inclusive) = 50 digits.
Thus, there are equal number of possible choices for each of the three numbers, which is equal to the Number of digits :
1st number = 50
2nd = 50
3rd = 50
Hence,
(50³). = 50 * 50 * 50 = 125,000
Maggie makes a scale drawing of a deck. The scale for the actual deck to the scale drawing is 7 ft to 1 in. The
dimensions of the deck are: 28 ft (Wide) by 17.5 ft (Tall). What is the WIDTH of the deck in the drawing?
Answer:
The width is 2.5 inches
Step-by-step explanation:
Here, we want to state the width of the deck in the drawing given the scale for the actual scale to the scale drawing.
The given ratio is 7 ft to 1 in
Now we will have 17.5 to x in
x * 7 = 17.5 * 1
7x = 17.5
x = 17.5/7
x = 2.5 inches

4. ∠JKL ≅ ∠JHG 4. Alternate interior angles
5. ∠GJH ≅ ∠KJL 5. Vertically opposite angles
6. ΔGHJ ≅ ΔLKJ 6. By ASA theorem of congruence
We have to prove the statement, ∠GHJ = ∠LKJ
Given; GH || KL, J is the midpoint of HK.
To prove; ∠GHJ = ∠LKJ
Given; J is the midpoint of HK,
By definition midpoint of a segment,
The midpoint is the middle part of the line segment J, it is equidistant from both endpoints it is the centroid of the segment of the endpoints.
JH ≅ HK
Then, by the property of alternate interior angles,
∠JKL≅ ∠JKH
Therefore, by the property of vertically opposite angles,
When two lines intersect they form four angles. Vertical angles are the angles that are opposite to each other. Any two intersecting lines form two pairs of vertical angles that are opposite to each other.
∠GJH ≅ KJL
By ASA congruence theorem,
When two triangles are congruent to each other - If two angles and the involved side of one triangle is equivalent to the two angles and the included side of the other triangle.
ΔGHJ ≅ ΔLKJ
Hence Proved.
