Describe and correct the error when dividing (x^3 - 5x + 3) by (x - 2).

- The number (divisor) on the leftmost should be -2.

- The numbers should be subtracted vertically, not added.

- The first line/row of coefficients should include a zero.

- The answer on the last column should be zero.

24

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

i believe the answer is c.

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.
