3 0

Let the numbers be x and y

x + y = 32
-
x - y = 8
__________
0x + 2y = 24
__________

The first equation minus the second.

2y = 24

y = 24/2

y = 12.

Recall: x + y = 32, y = 12

x + 12 = 32

x = 32 - 12

x = 20.

The two numbers are 20 and 12.

The area of the poster is (x^2+2x-15) inches the width is (x-3) inches calculate the dimensions of the poster board when x=14

givi [52]

Answer:

The poster is 11 inches wide and 19 inches in height.

Step-by-step explanation:

We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:

((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.

Therefore:

Height= 19 Inches

Width= 11 Inches

Total Area= 209 Square Inches
