Answer:
to gain upper- body strength
Step-by-step explanation:
The perimeter of a two-dimensional figure is always the sum of its sides.
The exercise mat has a perimeter (P) of <u>36 feet</u>. ...
Let length be <em>L</em>, and width be <em>W</em>.
P = 36
L = 2w
P=2(l+w)=2·(12+6)=36
L = 12 feet
W = 6 feet
Answer:
x = 4
Step-by-step explanation:
<u>Step 1: Set both parts equal to 0</u>
x - 4 = 0 and x - 4 = 0
<u>Step 2: Solve for x by adding 4 to both sides</u>
x - 4 + 4 = 0 + 4 and x - 4 + 4 = 0 + 4
x = 4 and x = 4
Answer: x = 4
