Raul makes aluminum poles in the shape of rectangular prisms. If he removes the covers on both ends, he can lower his cost per pole. How much aluminum in square feet will Raul save per pole if he chooses to remove the covers at the ends of the poles? Use the given figures.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
