x=21
Answer:
Step-by-step explanation:
How is 16 related to 2? We multiply 2 by 8, obtaining 16.
How is 8 related to 64? We multiply 8 by 8, obtaining 64.

2 is tenths
5 is hundreds
Answer:
x=−2 or x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x2−2x−3=5
Step 2: Subtract 5 from both sides.
x2−2x−3−5=5−5
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
