What are the leading coefficient and degree of the polynomial 9-10x^2-2x-15x^4

Leading coefficient = - 15

Degree = highest power on a variable = 4

Step-by-step explanation:

It might be easier to see if you rewrote the polynomial in the order it is normally presented.

Highest power goes on the left.

y = -15x4  -  10x^2 - 2x + 9

The leading coefficient (-15) is the number in front of the variable with the  highest power (x^4 or 4)

The highest power on a variable is the degree.

the answer is simply just 6n add the two together as they have an n

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
