Find the surface area of this triangular prism

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

a 90 degree rotation across the the origin followed by a reflection across the x-axis.

step-by-step explanation:

4 inches will get you 10.16 centimeters, but you can either do 10.1 or round up to 10.2. good luck and hope this : )
