Answer:
15
Explanation:
(x-5)(x+5)=200
FOIL Method (First, Outer, Inner, Last)
x^2-5x+5x-25=200
combine like terms
x^2-25=200
add 25 to both sides
x^2 = 225
Take the square root of both sides
x=15
Answer:
Mr. Conrad will need 14 cups of cherries to make 8 pies
Explanation:
Given;
A pie recipe = 1 3/4 cups of cherries = ⁷/₄ cups of cherries
8 pies will require how many cups of cherries ?

x = 14 cups of cherries
Therefore, Mr. Conrad will need 14 cups of cherries to make 8 pies
