That is way too much questions for one sitting. If you really struggle that much, download this app called photomath. You take a picture of one of the questions and then it instantly solves it and shows the work so you know how to do it.
For 16-25 however, you would need to rewrite your questions on a blank piece of paper with the variables substituted in. So let's say:
a + b² - (c-2).
You would need to rewrite it as the following in order for the app to solve it.
12 + 9² - (4 -2)
Answer:
y(y-2)(y+10)
Step-by-step explanation:
when factoring you work with similar concepts and get rid of what you can to make the equation simipler and get your answer like you take a y out of the equation to get y^2 and then reduce and then solve by grouping.
The prime factorisation for 58 is 2 x 29

<span>1.
-x = 2 - 3x + 6
-x + 3x = 8
2x = 8
x = 8/2
x = 4
2.
</span><span>Step 1: 2(3x − 4) = 8 + 2x + 4
Step 2: 5x − 6 = 12 + 2x </span>← wrong
The correct step: <span>Step 2: 6x − 8 = 12 + 2x
3.
</span>The next step is <span>2m = 8</span>
