. 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

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

answer: it is d
