Multiply all of the numbers together: 5 x 2 x 8 = 10 x 8 = 80 ways
For 16/18 it would be 8/9
For 10/15 it would be 2/3
Answer:
-30 i guess
Step-by-step explanation:
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
