Answer: The expression that represents the perimeter of the rectangle is given as

Perimeter= 4x +10

Step-by-step explanation:

Perimeter= 2l+2w =2( l+w)

Let the  width be  =x

And Length=x+5

So that the Perimeter =2l+2w becomes

Perimeter =2x +2(x+5)

Perimeter =2x+2x+10

Perimeter= 4x +10

Answer:

a must be 9

Step-by-step explanation:

Divide both sides of the given equation by 0.75, to isolate (a - 2):

a - 2 = 5.25/0.75 = 7

Then a - 2 = 7, and so a must be 9.

Answer:

Hello! answer: coordinates of E' are (16, 4)

Step-by-step explanation:

4 × 4 = 16 4 × 1 = 4 therefore the new coordinates are (16, 4)

The coordinate of E after dilation is (16, 4).

It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle DEF has coordinates:

D = (3, 4)

E (4, 1)

F = (1, -2)

The coordinates are dilated with a scale factor of 4.

This means,

Multiply all the coordinates by 4.

Now,

D = (3 x 4, 4 x 4) = (12, 16)

E (4 x 4, 1 x 4) = (16, 4)

F = (1 x 4, -2 x 4) = (4 , -8)

Thus,

The coordinate of E is (16, 4).

Answer:

The length of line segment FG is equal to the length of F'G'

The perimeter of pentagon CDEFG is equal to the perimeter of pentagon C'D'E'F'G.

Step-by-step explanation:

Given

CDEFG and C'D'E'F'G

Translation: 7 units up and 5 units left

Solving (a): Segment FG and F'G'

When a shape is translated, the resulting image will have the same lengths as the original image (i.e, translation does not change measurements)

Hence:

[tex]FG = F'G'[/tex]

Solving (b): Perimeter CDEFG and C'D'EF'G'

In (a), we established that lengths do not change during translation;

Hence:

The perimeter of the CDEFG and C'D'EF'G' will remain the same

Answer:

1) 5 : 7 : 8.75

2) Happy = 168 .    Juma = 210

3) Rima = 17800 .     Happy = 24920 .    Juma = 31150

Step-by-step explanation:

1) 5 : 7 : 8.75

Ratio Rima to Happy = 5:7

Ratio Happy to Juma = 4:5

7/4 = 1.75

1.75 x 5 = 8.75

Ratio = 5 : 7 : 8.75

2) Happy = 168 .     Juma = 210

Ratio = 5 : 7 : 8.5

120 / 5 = 24

Happy = 24 x 7 = 168

Juma = 24 x 8.75 = 210

3)17800 : 24920 : 31150

5 + 7 + 8.75 = 20.75

73870 / 20.75 = 3560

3560 * 5 = 17800 = Rima

3560 * 7 = 24920 = Happy

3560 * 8.75 = 31150 = Juma

Using exponentiation,

[tex]e^{lny} = e^{2.5}\\\textrm{But }e^{lny} \textrm{ is simply y (log rule)}\\\textrm{So we get}\\y = e^{2.5}\\\\\\\textrm{Substituting for y we get}\\\\5x + 3 = e^{2.5}\\x = (e^{2.5} - 3)/5\\[/tex]

Answer:

The total cost of adding wallpaper to the room is 487.20

Answer:

The total cost of adding wallpaper to the room is $487.20

Step-by-step explanation:

Basically, how I got the answer is:

1. The shorter sides of the rectangle are 12 and the longer sides are 14.

2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.

3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.

Hope this helps! :)

Answer:

Find half the area of the rectangle

Step-by-step explanation:

Given

See attachment for the Serek's steps

Required

Which can be used to determine the area of the original triangle

To do this, we simply analyze each step.

At step 2, where he joined two congruent triangles to form a parallelogram.

Half the area of the parallelogram will give the area of the original triangle (since both triangles are equal)

At step 3, where he decomposed the parallelogram to a trapezoid and a right triangle.

Half the sum of the areas of the resulting shapes (trapezoid and right triangle) will equal to the area of the original triangle but half the area of each shape will not amount to the area of the original triangle

At step 4, where the right triangle and the trapezoid are merged to form a rectangle.

The area of the rectangle will equal to the area of the parallelogram in step (2).

So, half the area of the rectangle will equal to the area of the triangle.

Hence, (b) is correct

Answer:

Total time taken to complete the job is 26 hours

Step-by-step explanation:

Fred's First Job

Total amount paid = 475 dollar

Total hours of work = 19 hours

Charge per hour = 475/19 = 25 dollars per hour

Fred's second job

Total amount paid = 720 dollar

Total hours of work = 26 hours

Charge per hour = 720/26 = 27.69 dollars per hour

Fred's third job

Amount paid = 1180

When amount paid was 720, charge per hour was 27.69

When amount paid is 1180, charge per hour is (27.69/720) * 1180 = 45.38

Total time taken to complete the job = 1180/45.38 = 26 hours

Answer:

When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).
