None of these. It is harder to carry the backpack full of books because it has more mass and more inertia so it needs more force to move than an empty backpack.

Some rectangles have an area of 36 cm². Let the variable W represent the width of these rectangles. Which expression represents

ZanzabumX [31]

Answer:

The perimeter of the rectangle is expressed as; $P = \frac{72 \ + \ 2W^2}{W}$

Step-by-step explanation:

Given;

area of the rectangle, A = 36 cm²

width of the rectangle, = W

Let L represent the length of the rectangle,

A = L x W

$L = \frac{A}{W} = \frac{36}{W}$

The perimeter of the rectangle is calculated as;

P = 2(L + W)

Substitute the value of L into the above equation;

$P = 2(L + W)\\\\P = 2 (\frac{36}{W} + W)\\\\P = 2 (\frac{36 + W^2}{W} )\\\\P = \frac{72 \ + \ 2W^2}{W}$

Thus, the perimeter of the rectangle is expressed as $P = \frac{72 \ + \ 2W^2}{W}$

Solve for x. Show your work.<br><br> - x < -12

Andrej [43]

All you have to do is move -x to the right side and -12 to the left side to remove the negative sign.
-x<-12 (Original)
0<-12+x (Add x to both sides)
12<x (Add 12 to both sides)
The answer is 12<x, or you can write it as x>12.
