Brian frosted a cake top shaped like a parallelogram with a base of 13 inches and a height of 9 inches. nancy frosted a triangular cake top with a base of 15 inches and a height of 12 inches . which cake's top had a greater area? how much greater was it?

Brain's parallelogram shaped cake has greater area as compare to Nancy's triangular cake.

Step-by-step explanation:

Given: For Brain's parallelogram shaped cake

The base of parallelogram = 13 inches

The height of parallelogram = 9 inches

The formula to calculate area of Parallelogram is given by :-

For Nancy's triangular cake

The base of triangle = 15 inches

The height of triangle = 12 inches

The formula to calculate area of triangle is given by :-

Clearly, 117 > 90

And Difference in areas =

Therefore, Brain's parallelogram shaped cake has greater area as compare to Nancy's triangular cake.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
