Question

ILL GIVE BRAINLY THING

The length of a rectangle is 4x - 5 inches. The width of the rectangle is x + 1 inches.

A) Write a quadratic function equation to model the area of the rectangle.


B) Then evaluate the function for (2).

Answer 1

Answer:

A) A = 4x^2 - x - 5

B) f(2) = 9

Step-by-step explanation:

area is L x W, so you multiply 4x - 5 with x + 1

A = (4x - 5)(x + 1)

which gives you

A = 4x^2 - x - 5

you would then plug in 2 for x which gives you your answer of

9

Hope this helps you :)
