A rectangle has an area of 3/2 square yards, if the width of the rectangle is 1/2 yard, what is the length of the rectangle, in yards?

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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.

x = 3 ± √(5+y)

∈3,600
