12. 125%
13. 137%
14. 526%
Step-by-step explanation:
divide the first number by the second number, then multiply that answer by 100
so kind of like: Number1 ÷ Number2 = x
then you do x × 100
and that's your answer
(all of my answers are rounded to the nearest percent)
The answer is D
You multiply the denominator with the whole number and and the numerator

You could solve this problem by either: Factoring or by using the Quadratic Formula.
SOLVING BY FACTORING STEPS
<em>STEP 1:</em><em> Move (2x−1)(x+1) to the left side of the equation by subtracting it from both sides.</em>
<em />
<em>STEP 2:</em><em> Simplify 2x^2+3x−(2x−1)(x+1).</em>
<em />
<em>STEP 3: </em><em>Simplify each term.</em>
<em />
<em>STEP 4: </em><em>Simplify by adding terms.</em>
<em />
<em>STEP 5:</em><em> Subtract 1 from both sides of the equation.</em>
<em />
<em>STEP 6: </em><em>Divide each term by 2 and simplify.</em>

Answer: B
Step-by-step explanation: Mr. Inderhees added 5 to each side of the equation for his first step to isolate the <em>x</em> term which in this case is 4x.
So when he added 5 to both sides of the equation, he got 20 = 4x.
