Answer:
Step-by-step explanation:
-x/8=12+11=23
-x=23*8=184
x=-184
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
First let's establish that the problem requires the border to be as long as the total perimeter of the rectangular bulletin board.
Therefore:
Total length of border = Perimeter of rectangular bulletin board
As a rectangle has a total of four sides with two equivalent longer sides and two equivalent shorter sides, we must multiply the value of each of the two sides by two.
Total length of border = 2 ( 2 ) + 2 ( 4 )
Total length of border = 4 + 8
Total length of border = 12 feet
12 > 10
ANSWER:
Therefore, 10 feet of border isn't enough.

to get volume, you must multiply all the numbers so once you multiply all of them, you'd get 1944000
Answer:
x^2-6x+9
Step-by-step explanation:
(x-3)^2
= x^2-6x+9
<span>The original cost of the camera is $120.
Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.
We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.
Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>
