Gerald purchases a rectangle plot of land. The length of the plot is 20 feet more than the width. Gerald also had a fence put around the entire perimeter of the plot, at a cost of $8 per linear foot. The total amount he spent on both the land and the fence was $10,560. Part B: Write an equation in one variable that can be used to find the width, X feet, of the plot. Express the equation in the form ax^2+bx+c. Provide evidence to support your answer. Write the equation below in simplest form.

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
