Cise 2: 1. If the x + 7y = 5 cuts the circle x2 + y2 = 25 at the points P and Q. Determine

i. the coordinates of P and Q.

ii. the midpoint of a line P Q​

the value of x is 28.2

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
