X ·( x + 1 ) = 600
x² + x = 600
x² + x - 600 = 0

x = ( - 1 - 49 ) / 2 = - 50 : 2 = - 25
x = - 25, x + 1 = - 24
( - 25 ) · ( - 24 ) = 600
Answer:
C ) - 25
Answer: I know about this question I’m struggling on it..
Step-by-step explanation:
Answer:
<em><u>f</u></em><em><u>(</u></em><em><u>x</u></em><em><u>+</u></em><em><u>3</u></em><em><u>)</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>6</u></em><em><u>x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>2</u></em><em><u>0</u></em>
Step-by-step explanation:

X = 4.
You have to distribute by multiplying -4 by the numbers between -3x and -2.
12x + 8 =60
Subtract the 8 from 60 to simplify the equation.
12x = 48
Divide 12 by 48 and get 4.
x=4
