Area of a rectangle is Length x Width

Length = 5x+4
Width = 4x-4

Area = 5x+4 * 4x-4

Multiply each term by the other terms then combine them:
5x *4x = 20x^2
5x*-4 = -20x
4*4x = 16x
4*-4 = 16

20x^2 -20x +16x -16

20x^2-4x -16

The answer is G

27 yd<br> 36 yd<br> What is the length of the hypotenuse?<br> C-<br> yards
dybincka [34]

Answer:

The length of the hypotenuse is: 45 yards

Step-by-step explanation:

Given

a=27 yd

b=36 yd

To Determine

Hypotenuse = c

Pythagorean Theorem

For a right-angled triangle with sides a, b, and c is defined as:

c=\sqrt{a^2+b^2}

as

a=27

b=36

so substituting a=27, b=36

c=\sqrt{27^2+36^2}

c=45 yards

Therefore, the length of the hypotenuse is: 45 yards

Help with 6? I really need all correct answers. Please help!
Lostsunrise [7]

Answer:

A

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

= \frac{2x+6}{3x} - \frac{\sqrt{x}-8 }{3x}

Since both fractions have a common denominator of 3x, then subtract the numerators leaving the denominator, that is the numerators simplified

2x + 6 - (\sqrt{x} - 8)

= 2x + 6 - \sqrt{x} + 8 = 2x - \sqrt{x} + 14

Hence

f(x) - g(x)

= \frac{2x-\sqrt{x}+14 }{3x} → A
