Question

The two shapes below are similar.This means the sides are proportional.The ratios can be set up as: 21\2×+3=51\34.Use cross multiplication to calculate the value of x

Answer 1

It is 21/2x +3 = 51/34.

With cross multiplicatiin, it beccomes 21/2x = 51/34 - 3.

Then 21 / 2x = 51 - 102 / 34.

Then 21 / 2x = -51 / 34.

Then now comex cross multiplication. 21 x 34 = - 51 x 2 x.

The final answer is of x is 7.
