I need to find the perimeter and area of the rectangle: the length is 4 in and the width is (2x - 4) in.

Area= (length) x (width) = (4) (2x - 4) = 8x - 16

Perimeter = (2 lengths) + (2 widths) = (8) + (4x - 8) = 4x

A = BL
P = 2(B + L)

A = area
P = perimeter
B = width
L = length

A = 4(2x - 4)
P = 2(4 + (2x - 4))

Need some other bit of information to solve, like a relationship between area and perimeter . . but i can't solve for x, A, or P . . when i can only develop two equations with the given problem information . . so . .that's all :)

Answer:

I think it is 3?

Step-by-step explanation:

3, -2 ≤ 0

-5, 0 < -2 ≤ 5

3, -2 > 5

The second two lines do not hold true, as -2 is less than 0 and 5, not greater. The only that is true is the first one, but I am not sure that is how you do it.1

Answer:

g(f(x)) = x

Step-by-step explanation:

You are given f(x) = -4x - 1 and g(x) = $\frac{x+1}{-4}$ . Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.

You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).

It will look like: g(-4x - 1) = $\frac{x+1}{-4}$

$\frac{(-4x-1)+1}{-4}$

Now evaluate the expression to solve the problem. Start by combining like terms.

$\frac{(-4x)}{-4}$

You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:

$x$
