1. f(-2) = 6 * 1/3^-2

f(-2) = 6 * 9

f(-2) = 54

2. y = -3 * 4^3

y = -3 x 64

y = -192

3. f(4) = 1/4 * 2^4

f(4) = 1/4 * 16

How would you write an expression using a variable for the area and perimeter of a square with side 2x-9

Paladinen [302]

Perimeter :
because there are four sides to a square and all sides are the same, the answer is 4(2x-9)
area:
area is basically length times width so the answer is (2x-9)(2x-9) or (2x-9)^2

The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units i

alina1380 [7]

Answer:

$\boxed {\boxed {\sf 48 \ meters }}$

Step-by-step explanation:

The perimeter is the sum of the side lengths.

A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

$p= 2l+2w$

The length is 20 meters and the width is 4 meters.

$p= 2(20 \ m )+ 2(4 \ m )$

Multiply.

$p= 40 \ m + 8 \ m$

Add.

$p= 48 m$

The perimeter of the rectangle is <u>48 meters. </u>
