The pair of figures to the right are similar. Compare the first figure to the second. Give the ratio of the perimeters and the ratio of the areas .

Given:

The pair of similar triangles.

Base of smaller triangle = 10 in

Base of larger triangle = 14 in

To find:

The ratio of the perimeters and the ratio of the areas.

Solution:

Ratio of perimeter of similar triangles is equal to the ratio of their corresponding sides.

The ratio of area of similar triangles is equal to the ratio of squares of their corresponding sides.

Therefore, the ratio of the perimeters is 5:7 and the ratio of the areas 25:49.

if you was gonna solve for a, a is a   < -12

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
