Answer:
18 + √3
Step-by-step explanation:
The product of a surd and its conjugate gives a rational number. Hence;
(18 - √3) (18 + √3)
=324 + 18√3 - 18√3 - 3
=321
A rational number does not contain any surd, hence the answer.

159.60
Step-by-step explanation:
If Joel gets 20% off, he still has to pay (100-20) or 80%
The cost of the tablet is now 190 * .80
Then he has to pay 5% sales tax.
The tax is the prices times 5% plus the original price
190 *.80 *(1+.05)
or 190 *.80 *(1.05)
Instead of adding the sales tax, he subtracted the sales tax.
The total he needs to pay is
190 *.80 *(1.05)
159.60

Answer:
-3, 7
Step-by-step explanation:
EG = 5, so the distance between E and G is five.
G can be 5 units to the right of E:
2 + 5 = 7
G has coordinate 7.
G can be 5 units to the left of E:
2 - 5 = -3
G has coordinate -3.
Answer: -3, 7
