Answer: x=−2 or x=8
Step-by-step explanation:
Step 1: Factor left side of equation.
2(x+2)(x−8)=0
Step 2: Set factors equal to 0.
x+2=0 or x−8=0
x=−2 or x=8
Section J has 20 rows....each row has 15 seats....so section J has (20 * 15) = 300 seats. If each seat costs $ 18, and all the seats are sold, then the amount of money collected would be : (300 * 18) = $ 5,400 <=
Answer:
A = 104 ft²
Step-by-step explanation:
We're given that the width of the rectangle is 8 so that's the value of w. All we have to do is just plug in 8 into the equation:
A=w²+5w
A=(8)²+5(8)
A=64+40
A = 104 ft²
Area = base * height
Height = area / base
Height = base sin x
Where x = angle between side and the base
16% = 0.16
'of' = multiplication
0.16 * 140 = 22.4
