Prompt: In unit 5 we have been talking about polynomials and their degree. Mr. McGill thinks the degree of this polynomial is 2 because it is the exponent in front. What mistake did Mr. McGill make and what should the correct answer be?

x2−6x12−4x+8

degree of the polynomial should be 12

Step-by-step explanation:

The mistake he did was that he was supposed to consider the highest power

The power of the term in front should

not be used if the term does not have the highest power

As we can see. the term with the highest power is 12

So we can say that the degree is 12 and not 2

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
