Answer:

x = -6 x=5

Step-by-step explanation:

x^2 +x -30 =0

Factor

What two numbers multiply to -30 and add to 1

6 * -5 = -30

6-5 =1

(x+6) (x-5) =0

Using the zero product property

x+6 =0 x-5=0

x+6-6=0-6 x-5+5=0+5

x = -6 x=5

–0.2(x – 20) = 44 – x

GarryVolchara [31]

$-0.2(x-20)=44-x\qquad\text{use distributive property}\\\\-0.2x+4=44-x\qquad\text{subtract 4 from both sides}\\\\-0.2x=40-x\qquad\text{add x to both sides}\\\\0.8x=40\qquad\text{divide both sides by 0.8}\\\\x=\dfrac{40}{0.8}\\\\x=\dfrac{400}{8}\\\\\boxed{x=50}$

Simplify (ignore my garbage camera quality ....)

monitta

Answer:

C. 3

Step-by-step explanation:

Given expression is:

$({3^{\frac{1}{7}})^7$

We know that the rules of exponents are used to solve these kind of questions.

When there is exponent on exponent like in this question 1/7 has an exponent of 7 , the exponents are multiplied.

So,

$=3^{(7*\frac{1}{7} )}$

The 7's will be cancelled out and remaining power will be 1

$=3^1\\=3$

Hence, option C is correct ..
