1 answer:

grandymaker [24]3 years ago

Answer:

The difference of two squares occurs when the middle term or "b" of your polynomial is absent. so the the "c" term would have to be the product of a single number, one positive and one negative. if c = 3 then x2 - 9 = 0 factors to (x+3)(x-3) = 0 and so on.

Quinzel and Joseph sell shoes. Last month Quinzel sold 18 less pairs

hichkok12 [17]

Answer:

Quinzel sold 17 pairs of shoes last month.

Step-by-step explanation:

Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.

Set up a system of equations:

$\left \{ {{Q=J-18} \atop {Q+J=52} \right.$

Solve for "J" from the first equation:

$J=Q+18$

Applying the Substitution Method, you get:

$Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17$
