Answer: The correct answer is Choice A.

In the problem, we are given a trinomial. The answers are all factored forms of the a trinomial.

We can use the FOIL method on each to determine if it matches the problem.

Choice A:
(x + 10)(x - 3)
x^2 - 3x + 10x - 30
x^2 + 7x - 30

Thankfully, Choice A matches. Otherwise, we would have to check the rest of them.

3. Find x.<br> 8x - 37<br> 5x + 17<br><br><br> I really need help with this
sveticcg [70]

Answer: here is your steps Simplifying

8x + -37 = 5x + 17

Reorder the terms:

-37 + 8x = 5x + 17

Reorder the terms:

-37 + 8x = 17 + 5x

Solving

-37 + 8x = 17 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-37 + 8x + -5x = 17 + 5x + -5x

Combine like terms: 8x + -5x = 3x

-37 + 3x = 17 + 5x + -5x

Combine like terms: 5x + -5x = 0

-37 + 3x = 17 + 0

-37 + 3x = 17

Add '37' to each side of the equation.

-37 + 37 + 3x = 17 + 37

Combine like terms: -37 + 37 = 0

0 + 3x = 17 + 37

3x = 17 + 37

Combine like terms: 17 + 37 = 54

3x = 54

Divide each side by '3'.

x = 18

Simplifying

x = 18
