Let's solve your equation step-by-step.
x2+x=12
Step 1: Subtract 12 from both sides.
x2+x−12=12−12
x2+x−12=0
Step 2: Factor left side of equation.
(x−3)(x+4)=0
Step 3: Set factors equal to 0.
x−3=0 or x+4=0
x=3 or x=−4
Answer:
x=3 or x=−4
The answer is a - yes, because of the associative property
Answer:
b = -1
Step-by-step explanation:
5 ^ ( 3b-1) = 5 ^ ( b-3)
since the bases are the same, the exponents are the same
3b-1 = b-3
Subtract b from each side
3b-1-b = b-3-b
2b -1 = -3
Add 1 to each side3
2b-1+1 = -3+1
2b = -2
Divide by 2
2b/2 = -2/2
b =-1
Answer:
<u>The correct answer is that AC = 4x - 2 or 2(2x - 1)</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
AD = 6x + 10
CD = 2x + 12
2. Let's find the length of AC
AC = AD - CD
Replacing with the real values:
AC = (6x + 10) - (2x + 12)
AC = 6x + 10 - 2x - 12
AC = 6x - 2x + 10 - 12
<u>AC = 4x -2 or 2(2x - 1)</u>
