Answer:
Step-by-step explanation:
Formula
A = L * W
Givens
W = W
L = W + 2
Solution
Area = L*W
Area = (W+2)*W = 80 Remove the brackets.
Area = W^2 + 2W = 80 Subtract 80 from both sides.
Area = w^2+2W-80=80-80 Combine
Area = w^2 +2W-80 = 0 Factor.
Area = (w+10)(w - 8) = 0
W + 10 = 0 won't work
W = - 10 which isn't possible
W- 8 = 0
W = 8
L = 8 + 2 = 10
The answer looks like A
In order to have a function we can't repeat any value in the x, therefore in order to have a function represented in the table the question mark must be 2

Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) 4x - 3 = 2x + 7 collect like terms
4x - 2x = 7 + 3
2x = 10 divide both sides by the coefficient of x
x = 5
b) 2x + 6 = 7x - 14 collect like terms
2x - 7x = -14 - 6
-5x = -20 divide both sidess by the coefficient of x
x = 4
Answer:
659.73
Step-by-step explanation:
i searched up surface area cylinder calculator to get the answer but incase u can't use that
A= 2(pi) r h + 2 (pi) r ^2
in this case it would be
A= 2 (pi) (7) (8) + 2(pi) 7^2
after that u should be able to get 659.73
if u didnt understand the explanation try searching up "surface area cylinder calculator" and it should pop up!
(my fault if the answer is wrong btw)
