attempt 1 out of 2

RS = 8

Step-by-step explanation:

Given that R is on QS , then

QR + RS = QS , substitute values

3x - 8 + 2x = 3x , that is

5x - 8 = 3x ( subtract 3x from both sides )

2x - 8 = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

RS = 2x = 2 × 4 = 8

if you mean

then it's c. 8, -7/3

but if you mean

then it is

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
