Answer:
perimeter is 12x-6
Step-by-step explanation:
perimeter is the sum of all sides
3(x+2) + 2x+11 + 7x-23
distribute the 3 in the first term, then combine 'like terms'
3x+6 + 2x+11 + 7x-23
3x+2x+7x + 6+11+(-23)
12x-6
First convert 22 to decimal form. You do this by dividing the percent by 100.
22 / 100 = .22
Then multiply the dollar amount by the percentage in decimal form.
$45 * .22 = $9.9
So 22% of $45 is $9.9.
Then you subtract $9.9 from $45.
$45 - $9.9 = $35.1
