Solve using long division.
(3x^2+7x-20) / (x+4)

show work on paper pls, it'll be more

Quotient is and remainder is 0.

Step-by-step explanation:

Given:

Dividend =

Divisor =

The long division is shown in the attachment.

Step 1: we need to divide with we first multiply with 3x we get the remainder as

Quotient as 3x.

Step 2: Now the dividend is and divisor now we will multiply with -5 we get the remainder as 0 and Quotient as

Hence Quotient is and remainder is 0.

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.
