Answer:

Step-by-step explanation:

Two similar polygons, means a similarity would exist in both polygons

Perimeter of a rectangle = 2(l +w)
Perimeter of the larger rectangle = 36 (because it's the largest figure)
equation becomes 36 = 2(L + W)
since L = 14, it becomes = 36 = 2(14 +W)
36 = 28 + 2W
2W = 36 - 28 = 2w = 8

w = 4.

Now we assume that since the rectangles are similar, they would have similar dimensions, in this case Width. so with this, we find length of smaller rectangle.

21 = 2(L + 4) = 21 = 2L + 8

2L = 21 - 8 = 2L = 13

L = 13/2 = 6.5.

lastly the product of the length of both polygons = 14 * 6.5 = 91.

Their Products length is 91

A.) f(x) = x^2 because 2 > 1. So f(2) = 4.

A is correct.

B.) f(x) = x^2 because 5 > 1. So f(5) = 25.

B is incorrect.

C.) f(x) = 2x because -2 < 1. So f(-2) = -4.

C is incorrect.

D.) f(x) = 5 because x = 1.

D is correct.

So the answer is A and D.

Pablo spends 15 hours on writing tasks
answer: twice as much=2 times this number
then twice as much= 7.5 times 2
7.5 times 2= 15hrs

Hello

hjlf

Answer:

1/10

Step-by-step explanation:

1 + 1/2 = 1 1/2

1 - 1/8 = 7/8

1 + 1/5 = 1 1/5

1 - 1/3 = 2/3

1 + 1/10 = 1 1/10

One and one tenth is closest to one because one tenth is the smallest amount that would need to be added or taken away to get exactly one. Hope I helped!
