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>

since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75
Answer: 7
Step-by-step explanation:
-if y is the width and the length of area k (see diagram), the difference between n and y is of 2 square sides, one at each side of y.
-therefore, assuming that n is a whole number and that there aren’t half squares, y must be a whole number too because, as previously said, n-y = 2 so y= n -2
-the only perfect square amongst the values for k you listed is 25, so taking n and y as whole numbers the only possible value for k is 25
-therefore y is 5 and n is 7 because n-y = 2 so y + 2 = n
2x - 3y = 8....subtract 2x from both sides
-3y = -2x + 8 ...divide both sides by -3
y = 2/3x - 8/3
Answer:
D. x + 4y + 7
Step-by-step explanation:
A constant term is a term that is a number with no variables (letters) attached to it.
In this case, D is your answer, for the term 7 is a constant, with no variables next to it.
