Jenae is sewing a quilt for her grandmother. She decides the area of the quilt will be x2 + 18x + 80 square feet. The length of the quilt is (x + 10) feet.

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

a) 7x=7

step-by-step explanation:

the answer is two. hope this !

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.
