The product is equal zero if one of the factors is equal zero.Therefore:
The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
Answer:
Step-by-step explanation:
Isolate the term of x from one side of the equation.
<h3>x-5≤10</h3>
<u>First, add by 5 from both sides.</u>

<u>Solve.</u>
<u>Add the numbers from left to right.</u>


- <u>Therefore, the solution is x≤15, which is our answer.</u>
I hope this helps you! Let me know if my answer is wrong or not.
All you have to do, is combine like terms. Let's go through it:

Arrange it so you can easily combine like terms:

So, your answer for the sum is 1) 7x² - 10x + 2
The 3rd answer because -3 is the smallest y intercept
