If the ratio of the areas of two similar polygons is 25: 49, what is the ratio of the corresponding side length

5:7

Step-by-step explanation:

Ratio of the areas of similar shapes is equal to the square of the scale:

A₂ / A₁ = r²

Ratio of the side lengths of similar shapes is equal to the scale:

s₂ / s₁ = r

Therefore:

A₂ / A₁ = (s₂ / s₁)²

25/49 = (s₂ / s₁)²

s₂ / s₁ = 5/7

The ratio of the side lengths is 5:7.

5 : 7

Step-by-step explanation:

Given 2 similar figures then

ratio of sides = a : b

ratio of areas = a² : b²

Here the ratio of areas = 25 : 49, hence

ratio of sides = : = 5 : 7

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

2, 2, 2 or -4, 20, 29
