It’s 6,950 because if you do long division this is what you get
the constant term is 12
All the other terms have variables attached to them
The correct answer would be J
(x^2 +x )is the area of the office.
for x=12 the area is 156 sq.feet
F=5 dollar bills
t=twent dollar bills
38 total bills
f+t=38
400 in bills
400=5f+20t
we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation
-5f-5t=-190
5f+20t=400 +
0f+15t=210
15t=210
divide both sides by 15
t=14
subsitute
t+f=38
15+f=38
f=23
23 five dolar bills
15 twenty dollar bills
