R^2+3r+5-r^3/r is a quadratic/cubic/linear polynomial?
Sergeu [11.5K]

r^2+3r+5-r^3/r is  a linear polynomial

S<u>tep-by-step explanatio</u>n:

based on the highest power of the variables of a polynomial, it can be classified as linear,polynomial, quadratic polynomial,cubic polynomial etc.

In a linear polynomial, the highest power of the variable is 1. The general form of a linear polynomial is ax+b

In a quadratic polynomial, the highest power of the variables is 2.The general form of quadratic polynomial is ax^2+bx+c

In a cubic polynomial,the highest power of variable is 3.The general form of cubic polynomial is ax^3+bx^2+cx+d.

Take the given question and simplify it

r^2+3r+5-r^3/r=r^2+3r+5-r^2\\=3r+5

It is of the form ax+b. Hence it is  a linear polynomial.

The sum of three consecutive even numbers is 114. what is the smallest of the three numbers?​
saul85 [17]

Answer:

36

Step-by-step explanation:

Let's let n be any number.

If we multiply n by 2, we get 2n. Since anything multiplied by 2 is even, 2n <em>must</em> be even. Therefore, let 2n be our first number.

So, the consecutive even number will be (2n+2) followed by (2n+4).

We know that their sum must be 114. Therefore, we can write the following equation:

(2n)+(2n+2)+(2n+4)=114

Solve for n. Combine like terms on the left:

6n+6=114

Subtract 6 from both sides:

6n=108

Finally, divide both sides by 6. Therefore, the value of n is:

n=108/6=18

Therefore, our first even number is 2n or 2(18) which equates to 36.

And the consecutive even numbers will be 38 and 40.

So, the smallest of them, the first term, is 36.
