Harrison expanded the square flower garden in his backyard. He made one side 3 feet longer and the other side 6 feet longer. The expanded rectangular flower garden has an area of 148 square feet.

Use the drop-down menus to write an equation to model this situation.

Write an equation to represent the area of the expanded flower garden.

• = 148

65x65feet originally

Step-by-step explanation:

6x3=18

148-18=130

130/2=65

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
