Answer:

2x^2-5x-12

Step-by-step explanation:

a rectangle has a length of 2x+3 and a width of x-4 find the area

------------

Area = length * width

-------------------------

A = (2x+3)(x-4)

---

A = 2x(x-4)+3(x-4)

 

---

A = 2x^2-8x+3x-12

How many computers must the AB Computer Company sell to break even? Let x be the number of computers.
Eduardwww [97]

Answer:

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

R(x)=1.5x -----> equation A

C(x)=145+\frac{1}{4}x ----> equation B

where

C is the cost function

R is the revenue function

x is the number of computers sold

we know that

Break even is when the cost is equal to the revenue

so

equate equation A and equation B

1.5x=145+\frac{1}{4}x

Solve for x

subtract 1/4x both sides

1.5x-\frac{1}{4}x=145

1.5x-0.25x=145

1.25x=145

Divide by 1.25 both sides

x=116

therefore

The Company AB must sell 116 computers to break even
