What is the perimeter of quadrilateral ABCD? a(-3,2) b(4,2) c(3,-3) d(-3,3)
lord [1]

Answer:

Perimeter will be = 21.6

Step-by-step explanation:

As we know the formula to get the length between two points A and B having coordinates A(x,y) and B (a,b) is

AB = √(x-a)²+(y-b)²

We will use this formula to get the lengths of all sides of the quadrilateral.

AB=√(4+3)²+(2-2)² =√7² =7

BC = √(3-4)²+(-3-2)²=√(-1)²+(-5)² = √1+25=√26 = 5.1

CD = √(3+3)²+(-3-3)² = √6²+(-6)² = √72 = 8.5

DA = √(-3+3)²+(3-2)² =√1 = 1

Since perimeter of the quadrilateral = sum of lengths of all sides

Perimeter = 7 + 5.1 + 8.5 + 1 = 21.6

An Internet service provider charges $9.95/month for the first 20 hours and $0.50 for each additional hour. Write an expression
inn [45]
I= 9.95 + .5h

20-35=15
I = 9.95+.5(15)
9.95+7.5
I = 17.45

If you used the internet for 35 hours, your bill would be $17.45
