. A rectangular banner has a length that is two feet shorter than twice its height, h. If the expression represents the area of the banner is shown below, what is the height of the banner whose area is 60

height h = 6 ft

Step-by-step explanation:

Given;

Area = 60 ft^2

length l that is two feet shorter than twice its height, h.

Length l = 2h - 2

Area = length × height = l × h = 60

Substituting l = 2h - 2

(2h-2) × h = 60

2h^2 - 2h = 60

Divide through by 2,

h^2 - h - 30 = 0

Solving the quadratic equation, we have;

(h-6)(h+5) = 0

h = 6 or h = -5

Since h cannot be negative;

height h = 6 ft

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
