Answer:

Step-by-step explanation:

x^2 + 2x - 3 = (1)^2 + 2(1) - 3 = 0 for x = 1

                       (2)^2 + 2(2) - 3 = 5 for x = 2

                        (3)^2 + 2(3) - 3 = 12 for x = 3

x^3 + 5 = (1)^3 + 5 = 6 for x = 1

               (2)^3 + 5 = 13 for x = 2

               (3)^3 + 5 = 32 for x = 3

x^2 + 5x + 4 = (1 )^2 + 5(1) + 4 = 10 for x = 1

                       (2)^2 + 5(2) + 4 = 18 for x = 2

                        (3)^3 + 5(3) + 4 = 46 for x = 3

A rectangle school banner has a length of 44 inches, a perimeter of 156 inches , and an area of 1496 square inches. The cheerlea
Andrej [43]
Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.

So, 44 ÷ 4 = 11.

For the perimeter, 156 ÷ 4 is 39.

For the area, you have to do A=bh
(Area = base × height)

The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.

Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2

The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in

I hope that helps!
