Robert wants to buy wrapping paper to cover a square-shaped painting. to determine the size of the wrapping paper needed for the painting, he adds 9 inches to each side of the painting. robert picks out wrapping paper with a perimeter of 120 inches to wrap the square-shaped painting.
what are the side lengths of the painting and the wrapping paper?

The side length of the painting and the wrapping paper are 21 inches and 30 inches respectively.

Step-by-step explanation:

Let x be the side length ( in inches ) of the square shaped painting,

∵ After adding 9 inches in each side,

The new side length of the square = (x+9) inches, ( wrapping paper side length )

∵ Perimeter of a square = 4 × (side length)

Thus, the perimeter of the new square = 4(x+9) in

According to the question,

4(x+9) = 120

x + 9 = 30

x = 21

Hence, the side length of the square = 21 inches,

And, the side length of the wrapping paper = 30 inches

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it

pretty sure 750 each month!
