Split the second term in 3x^2 + 31x + 36 into two terms

3x^2 + 27x + 4x + 36

Factor out common terms in the first two terms, then in the last two terms

3x(x + 9) + 4(x + 9)

Factor out the common term; x + 9

(x + 9)(3x + 4)

i think it is c, not positive though

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
