I believe the answer is 3. Im not sure so sorry if you get it wrong
Hello there! The value of x is 20 or -20
"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.
Step-by-step explanation:

First, we simplify 5² and 4²

Multiply the whole equation by 25 to get rid of the denominator.

Square both sides and solve the equation.

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

Answer:
0

Well, what I would do is line it up so you can cancel things out. I.e.:
(3x*2y-2)3
(9xy*3)3
Both of the 3s can cancel out
3x*2y-2
9xy*3
2y-2
3y*3
2y/3y-2/3=2/3-2/3=0

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!
Answer:
363-138=-5x
Step-by-step explanation:
Let c = cost
We know that the total cost is $363:
363-??????
We also know that he spent $138 on parts:
363-138?????
And we are solving for the cost of labor per hour:
363-138=5x
We can use this equation to find the total cost of labor per hour.
Hence, your equation will be 363-138=5x
Answer:
2x(x + 3)(2x - 1)
Step-by-step explanation:
Given
4x³ + 10x² - 6x ← factor out 2x from each term
= 2x(2x² + 5x - 3) ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 5
The factors are + 6 and - 1
Use these factors to split the x- term
2x² + 6x - x - 3 ( factor the first/second and third/fourth terms )
= 2x(x + 3) - 1(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x - 1)
Thus
4x³ + 10x² - 6x = 2x(x + 3)(2x - 1) ← in factored form
