Question

The triangles below are similar. 3x+3

Answer 1

The answer would be 3(x+1)

Answer 2

Answer:

x = 11

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{3x+3}{x+7}$ = $\frac{38}{19}$ = 2 ( multiply both sides by x + 7 )

3x + 3 = 2(x + 7)

3x + 3 = 2x + 14 ( subtract 2x from both sides )

x + 3 = 14 ( subtract 3 from both sides )

x = 11
