Step-by-step explanation:

The ratio of the perimeters = the scale

P₂ / P₁ = 6 / 4 = 3 / 2

The ratio of the areas = the square of the scale

A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4

Same for the triangles:

P₂ / P₁ = 6 / 3 = 2

A₂ / A₁ = (6 / 3)² = (2)² = 4

Multiply 4(x+6)/(x−2)⋅(x+10)/24(x+6)

liq [111]

Answer:

Step-by-step explanation:

4(x+6)/(x-2)*(x+10)/24(x+6)

First we do 4(x+6)

4x+24

Then we do 24(x+6)

24x+144

So we plug it in

4x+24/x-2*x+10/24x+144
