White raven [17]
To find the area of a triangle, use 1/2 x b x h.  3 x 4 = 12    1/2 of 12 = 6

There are two triangles, each of these are 6      6 x 2 = 12

The bottom shape is 3.5 x 3      3.5 x 3 = 10.5

The front shape is 3.5 x 5      3.5 x 5 = 17.5

The back shape is 3.5 x 4        3.5 x 4 = 14

Add them all together: 14 + 17.5 + 10.5 + 12 = 54

Your answer is 54!

Mama L [17]

Answer:

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y

Step-by-step explanation:

Given:

Cost of X company = \$ 0.35+(\$0.05\times 1 \ minute)

Cost of Y Company =\$ 0.15+(\$0.04\times 1 \ minute)

for n minutes

Cost of X company for n minutes = \$ 0.35+(\$0.05\times n \ minute)

Cost of Y Company for n minutes =\$ 0.15+(\$0.04\times n \ minute)

Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes

Difference for n minutes = (\$ 0.2+\$ 0.01n)=(0.2+0.01n)\times 10^2 \ cents

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y
