Answer:
x=2 or x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
(x+6)(x−4)=−16
Step 1: Simplify both sides of the equation.
x2+2x−24=−16
Step 2: Subtract -16 from both sides.
x2+2x−24−(−16)=−16−(−16)
x2+2x−8=0
Step 3: Factor left side of equation.
(x−2)(x+4)=0
Step 4: Set factors equal to 0.
x−2=0 or x+4=0
x=2 or x=−4
Answer:
(8,8)
Step-by-step explanation:
7*(60+3)=7*60+7*3= 420+21=441
Answer:
B.
Step-by-step explanation:
21 X 2 = 42
42-7 = 35
35 + 21 = 56
You should plug the x and y values into the original equations to get your b value. You should get a b value of 7. Your new equation should be y=2x+7
