Answer:
4
Step-by-step explanation:
The highest/exponent of the variable is the degree of the polynomial.

Here, the highest degree of the variable m is 4
So, degree of the polynomial = 4
Answer:x=9
Step-by-step explanation:
-4=5-x
Add x on both sides
x-4=5
Add 4 on both sides
x=5+4
Solve
x=9
The proportion that could be used to solve for the variable is:
; p = 12 ⇒ b
Step-by-step explanation:
Direct proportion means that two (or more) quantities increase or decrease in the same ratio
- y = k x is the equation of direct proportion, where k is the constant of proportionality
is the another way to write a proportion
The number of pencils and the cost of them is increased together or decreased together
∴ The number of the pencils and their costs are in direct proportion
- By using the 2nd rule above
∵ The cost of the 7 pencils is $1.68
∵ The cost of p pencils is $2.88
∴ 
The proportion that could be used to solve for the variable is: 
∵ 
- By using cross multiplication
∴ p × 1.68 = 7 × 2.88
∴ 1.68 p = 20.16
- Divide both sides by 1.68
∴ p = 12
The value of variable p is 12
