Answer:

7x^2+5x

Step-by-step explanation:

Given

Polynomial 1: 9x^2+8x

Polynomial 2: 2x^2+3x

We have to find subtraction of both

So,

9x^2+8x - (2x^2+3x)

First of all the brackets will be eliminated by multilying the minus sign

9x^2+8x-2x^2-3x

The terms with same power of variable will be written together

9x^2-2x^2+8x-3x

=7x^2+5x ..

The thrill of riding a roller coaster is​ addictive, both for its users who take the​ ride, and for the designers and engineers
Makovka662 [10]

Answer:

The quantitative variables in this case are:

A.  Speed

D.  GForce

E.  Height

G. Duration

H. Numinversions

J.  Length

Step-by-step explanation:

One criteria to differentiate qualitative variables from quantitative variables is to determine if mathematical calculations over these variables makes sense.

If it makes sense, it is a quantitative variable.

For example, binary variables, although they can be represented by 0 and 1, would be a qualitative variable.

The quantitative variables in this case are:

A.  Speed

D.  GForce

E.  Height

G. Duration

H. Numinversions

J.  Length

They all will be represented by numbers for which mathematical operations make sense.

Find the following measure for this figure. Lateral area = 24 square units 48 square units 96 square units
Savatey [412]
We are asked to solve for the lateral surface area of the cylinder such that the formula that we can used is Lateral Surface Area = 2pi*r*h where "r" represents the radius of the cylinder and "h" represents the height of the cylinder. In this problem, we are given with the following values:
r = 4 inches
h = inches
Solving for the lateral surface area, we have it:
L.S.A = 2 *pi * r* h
L.S.A = 2*pi*4*6
L.S.A = 48pi units squared

The answer is 48pi unit2.
