Q. A customer wants to re-carpet a living room and hallway. You charge $5.99 per square yard to remove old carpet and $4.50 per square yard to install the new carpet. The carpet
and pad they selected are $16.99 and $3.00 per square yard, respectively. The living room is
171 by 20 feet and the hall is 4 by 12 feet. About how much should you charge for this job?

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
