First u need to multiply the 3 with the numbers inside of the parenthesis. it equals......1+36x+18
Let's say David's age right now is x years
x + 6 = 2(x - 7)
x + 6 = 2x - 14
x = 20
Therefor David is 20 years old
(1+0.30)=1.30
56 (1.3) = 72.80
The price of the pair jeans before the sale was $72.80

Answers: PA and PC</h3>
Explanation:
Segments PB, PA and PC are all radii of the same circle. We call this circle the circumcircle, with point P as the center of this circle.
To determine the location of P, we construct at least two perpendicular bisectors as the diagram shows. Segments PR, PS and PT are perpendicular bisectors of AB, AC, and BC in that order.
