Write a simplified polynomial expression in standard form to represent the area of the rectangle below.

JulijaS [17]

Given:
Rectangle shape.
One side: 5x + 2
other side: x - 4

Area = length * width
Area = (5x+2)(x-4)
A = 5x(x-4) +2(x-4)
A = 5x² - 20x + 2x - 8
A = 5x² - 18x - 8

Please help me I’m struggling :’(

Vesna [10]

Answer:

B. $x = \sqrt{40}$

Step-by-step explanation:

Using Pythagorean theorem, find the value of x.

Pythagorean theorem is given as $c^2 = a^2 + b^2$

Where,

c is the longest side of a right angled ∆ = the hypotenuse = x

a and b are legs of the right angled ∆ = 2 and 6

Plug in the values into the equation and solve for x

$x^2 = 2^2 + 6^2$

$x^2 = 4 + 36$

$x^2 = 40$

$x = \sqrt{40}$
