Answer:
C. 3, -7
Step-by-step explanation:
x^2 +4x-21 =0
Factor
What 2 numbers multiply to -21 and add to 4
7*-3 = -21
7-3 = 4
(x+7) (x-3) =0
Using the zero product property
x+7 =0 x-3=0
x+7-7=0-7 x-3+3=0+3
x = -7 x=3

Answer:
T=30
Step-by-step explanation:
1) inverse mean opposite, so they want us to solve this equation using the opposite operation
So we can see here that 5 is being multiplied with t, so we should perform the opposite operation, division.
So
5t=150
(divide both sides by 5)
T=30
