Suppose that 18 inches of a wire cost 72 cents. at the same rate, how many inches of wire can be bought for $.56

that’s wrong it’s 14

Step-by-step explanation:72 divided by 18 is 4

And then 56 divided by 4 is 14

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
