Answer: -3a^2 + 11a

Step-by-step explanation:

4a - (a x 3a) + 7a - Multiply first to get 4a - 3a^2 + 7a

4a - 3a^2 + 7a - Add like terms (a terms) to get -3a^2 + 11a

So the answer in -3a^2 + 11a

Kevin works as a salesperson at a store that specializes in custom made computers. He earns a base pay of 325$ per week and a co

kondaur [170]

ANSWER:

Kevin made $800 in commissions last week.

EXPLANATION:

Since we know that he only makes money in two ways, by base salary and commission, we know that added together they equal his whole pay.

Therefore we can set up the following equation and solve for his commission amount.

Total Pay = Base Pay + Commissions.

1125 = 325 + Commissions.
800 = Comissions.

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13

shepuryov [24]

Answer:

Hence, the surface area of cone is:

282.6 cm^2 which is approx 283 cm^2.

Step-by-step explanation:

We are given:

The circular base of a cone has a radius of 5 centimeters.

i.e. r=5 cm.

The height of the cone is 12 centimeters

i.e. h=12 cm.

The slant height is 13 centimeters.

i.e. l=13 cm.

Now we know that the surface area(S.A.) of cone is given by:

$S.A.=\pi r(l+r)$

Hence by putting the value of l,r and π in the formula we get:

$S.A.=3.14\times 5\times (13+5)\\\\S.A.=15.7\times 18\\\\S.A.=282.6$

Hence the surface area of cone is 282.6 cm^2 which is approx 283 cm^2.
