Answer:

924 cm²

Step-by-step explanation:

The surface area is equal to the area of the two triangles + area of the three rectangles.

Area of two triangles:

12 × (9+5) × 1/2

= 84

84(2) = 168

Area of the three rectangles:

15 × 20 + 13 × 20 + 14 × 20

= 840

840 + 84

The surface area of the triangular prism is 924 cm².

What is the solution for C when 10 C minus f equals -13 + c d
andreyandreev [35.5K]

Answer:

C would be equal to (f - 13)/(10 - d)

Step-by-step explanation:

In order to find this, you must manipulate the equation so that the left side has every term with a c in it. Then you can isolate it by dividing and find what it is equal to.

10c - f = -13 + cd -----> Add f to both sides

10c = f - 13 + cd -----> Subtract cd from both sides

10c - cd = f - 13 ------> Pull out c

c(10 - d) = f - 13 -----> Divide by (10 - d)

c = (f - 13)/(10 - d)
