The area of a rectangle is x² + 2x -15. If its length is x + 2 units, what is its width?

Luda [366]

Length of the rectangle is 8 units

Step-by-step explanation:

Step 1: Find the length, let width be x.

Area of the rectangle = 48 units

Length = x + 2

⇒ Area = Length × Breadth

48 = x (x + 2)

48 = x² + 2x

x² + 2x - 48 = 0

x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)

x(x + 8) - 6(x + 8) = 0

(x - 6)(x + 8) = 0

⇒ x = 6, -8 (negative value is neglected)

∴ x = 6

x + 2 = 8

The average revenue of a TV manufacturing unit is given by r(x)=75x^2-5x^3/2 where x is the number of TVs sold by the firm. Find

olga nikolaevna [1]

Answer:

The total revenue generated by the firm is:

$P(x) = 75x^3-5x^{\frac{5}{2}}$

Step-by-step explanation:

The average cost per TV is:

$r(x) =\frac{P(x)}{x}$

Where x is the number of televisions sold and P is the firm's income for all the televisions sold

In this problem we know the equation r(x).

Then P(x) will be:

$P(x) = x*r(x)$

Therefore if $r(x)=75x^2-5x^{3/2}$ then

$P(x) = x*(75x^2-5x^{3/2})$

$P(x) = 75x^{2+1}-5x^{\frac{3}{2}+1}\\\\P(x) = 75x^3-5x^{\frac{5}{2}}$
