According to the rational root theorem, which number is a potential root of f(x) = 9x8 9x6 – 12x 7?

The options of the problem are

we have

we know that

The Rational Root Theorem states that when a root 'x' is written as a fraction in lowest terms

p is an integer factor of the constant term, and q is an integer factor of the coefficient of the first monomial.

So

in this problem

the constant term is equal to

and the first monomial is equal to -----> coefficient is

therefore

the answer is the option

D.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
