Answer:
see explanation
Step-by-step explanation:
Expand the right side and then compare like terms with the left side.
(q + 2
)²
= q² + 4q
+ 12
= q² + 12 + 4q
Compare like terms with 28 + p
Comparing the
terms gives
p = 4q
and comparing the constant terms gives
q² + 12 = 28 ( subtract 12 from both sides )
q² = 16 ( take the square root of both sides )
q = ±
= ± 4
Hence
p = 4q = 4 × ± 4 = ± 16
Answer:
It would cost her $45.
Step-by-step explanation:
25 dollars divided by 5 shirts = 5 dollars per shirt.

Answer:
<u>x=-2</u>
Step-by-step explanation:
the while goal of this is to isolate the x on one sideso x= the answer, so
first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you <u>x=-2.</u>
