Pl help Question 1: Ezra went on a shopping trip to Ashland. He purchased an oil painting originally priced at $50 but discounted 60%. If sales tax in Ashland is 15%, what was the total cost?

4.28095238095 that is the answer

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

c. -4 slope formula is (y2-y1)/(x2-x1)
