What is the degree of the polynomial 3xy2z−2z5+23y2z4 ?
2
4
5
6

6 is the degree of polynomial.

Step-by-step explanation:

The given polynomial is

In this polynomial we have to tell its degree.

First we will calculate the degree of each term of the polynomial given.

3xy²z = Degree is 4 ( x-1, y-2,z-1 total 1 + 2 + 1 = 4)

= Degree is 5 (z - 5)

= Degree is 6 (y -2, z-4 total 2 + 4 = 6)

Therefore the highest degree of the polynomial will be the degree of polynomial.

Answer is Option 4. Degree - 6

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.
