1st person to answer gets ! which expression represents x^2+7x-60 in factored form, and how? a.(x-5)(x-12) b.(x-5)(x+12) c.(x-6)(x+10)

B

Step-by-step explanation:

x² + 7x - 60

              ∧

           -1   +60 = 59

           -2  +30 = 28

           -3  +20 = 17

           -4   +15 = 11

           -5   +12 = 7 ← This is the b-value!

           -6   +10 = 4

Factors are (x -5) and (x + 12)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
