To solve this equation we must first plug in 5 for x.

$\frac{1}{3}$ <span> (5 - 4x)
</span>↓
$\frac{1}{3}$ (5 - 4 · 5)

The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

$\frac{1}{3}$ (5 - 4 · 5)

$\frac{1}{3}$ (5 - 20)

The next step would be to subtract both of the numbers within the parenthesis.

$\frac{1}{3}$ (-15)

Now we must multiply.

- $\frac{1}{3}$ · 15 = - $\frac{1×15}{3}$

- $\frac{15}{3}$

Now we simplify our answer to get our final answer.

Find the area of a square with a side measure of 3x − 6 feet. Question 5 options: 9x2−36x+36 sq. ft. 9x2−6 sq. ft. 9x2+36x+36 sq

Sergeeva-Olga [200]

Answer:

9x^2 - 36x + 36 sq. ft. (the first option).

Step-by-step explanation:

Area of a square of side d = d^2.

So area of this square = (3x - 6)^2

= (3x - 6)(3x - 6)

= 3x(3x - 6) - 6(3x - 6)

= 9x^2 - 18x - 18x + 36

= 9x^2 - 36x + 36 sq ft.

Use the quadratic formula to solve the equation x2+7x

monitta

The solution of the equation x2+7x is 0, -7 using the quadratic formula.

Step-by-step explanation:

x2 + 7x = 0

-b ± √ b2 - 4(ac)/ 2a

substitution,

a = 1, b = 7, c = 0

= -7 ± √(7)2 - 4(1 x 0) / 2 x 1

= - 7 ± 7 / 2

x = 0 , -7
