You buy a pair of jeans (j) that cost $12, two pair of socks (s) for $2 each, and three tops (t) that cost $6 each. Which expression represents this situation and how much did you spend?

Step-by-step explanation:

1*12 + 2*2 + 3*6 = 12 + 4 +18 = $34

(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

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
