Lisa has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

398

Step-by-step explanation:

To find the answer all you have to do is to find the area of this shape. Area= Base x Height.

First step: Is to subtract 26-6. That will give you 20. 

Second Step:  That will give you 200 because 20 × 20= 400 / 2 = 200.

Third Step: Calculate the triangles by cutting them. . That will give you 18 because 6 × 6= 36, and 36 / 2 = 18.

Fourth Step: Multiply 30x6. 30x6=180

Final Step:Add 200+180+18. That will give you 398. 

Lisa has to cut 398 square feet of her grass.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
