Answer:
4w + 9
Step-by-step explanation:
Area of rectangle = length x width (or base x height, depending on how you look at it).
It is given to you that:
Area = 8w + 18
Length = 2
Let: width = x
Plug in the corresponding terms with the corresponding words:
8w + 18 = 2x
Isolate the variable, x. Divide 2 from both sides of the equation:
(8w + 18)/2 = (2x)/2
x = (8w + 18)/2
w = (8w)/2 + (18)/2
w = 4w + 9
4w + 9 is the expression that represents the width of the rectangle.

Answer:
the awnser is 3
Step-by-step explanation:
No, the first one you did get correct but the second, third and fourth are wrong here is you correct answer.
F(x) = 4x - x to the second power
So you substitute x for the numbers under x.
The second answer under f(x) is wrong it’s suppose to be...
F(x) = 4(0) - 0 to the second power the answer is 0.
The third answer under f(x) is also wrong the answer is...
F(x) = 4(-1) - -1 to the second power the answer is -3.
Looking back I see that under x the number 2 in f(x) is wrong also.
The answer Is f(x) = 4(2) - 2 to the second power equals 4.
Is this math
