3. A student is painting an accent wall in her bedroom. The length of the wall is three feet more than
its width. The area of the wall is 130 square feet. What are the dimensions of the accent wall?

The dimensions of the wall is:  length = 13 feet and width = 10 feet.

Step-by-step explanation:

Let the length and width of the wall be represented by L and W,

then by the question:

                                      L = 3+W...............................................(1)

And,

                                      Area = L* W

                                  or, L *W = 130.........................................(2)

solving equation 1 and 2,

                                      (3+W) W = 130

                                  or, -130 + 3W + = 0

                                  or,    + 13W - 10W - 130 =0

                                  or, W(W+13) -10(W+13) = 0

                                 or, W =10, W= -13

Taking positive value we get, W= 10 feet

And, L = 3+10 = 13 feet

Hence the length and width of the wall is 13 feet and 10 feet.

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
