A. All real numbers

Explanation:
Using distributive property, distribute the 2 to the (x + 1).
This gives us
2x+2 = 2x+2
Since these equations are equal on both sides, they will be equal no matter what number you use as x.

Hope this helps! Please mark brainliest if you can :)

Repost: Каков объем этой прямоугольной призмы?

So first of all we should know that the <u>rectangular prism is a cuboid.</u>

$\\ \\$

<h3>Given :-</h3>

heigth = 9 in.
Length = 5 in.
Width = 4 in.

$\\$

Volume of cuboid.

$\\$

<h3>Solution:-</h3>

We know:-

$\bigstar \boxed{ \rm volume \: of \: cuboid = length \times width \times height}$

$\\ \\$

So:-

$\dashrightarrow \sf volume \: of \: cuboid = length \times width \times height \\$

$\\ \\$

$\dashrightarrow \sf volume \: of \: cuboid = 9 \times 5 \times 4 \\$

$\\ \\$

$\dashrightarrow \sf volume \: of \: cuboid = 45 \times 4 \\$

$\\ \\$

$\dashrightarrow \bf volume \: of \: cuboid = 180 {in}^{3} \\$

Therefore option C is correct .

If an aerosol can contained 350mL of CFC gas at a pressure of 5.1 atm , what volume would this gas occupy at 1.0atm?

4vir4ik [10]

For this case we have the following relationship:
P1V1 = P2V2
Clearing volume 2 we have:
V2 = (P1 / P2) * (V1)
Substituting values we have:
V2 = (5.1 / 1.0) * (350)
V2 = 1785 mL
Answer:
this gas would occupy 1785 mL at 1.0atm

Perform the indicated operation. Simplify the result in factored form.

vfiekz [6]

Answer:

$\frac{a+1}{(a-2)(a-1)(a-1)}=$

Step-by-step explanation:

1. Approach

The easiest method to solve this problem is to factor the expression. In order to subtract (or add) two fractions, both fractions have to have common denominators. When the fractions are factored one can easily see the least common denominator. Convert both fractions to the least common denominator by multiplying the numerator (number over the fraction bar) and denominator (number under the fraction bar) by the value such that both fractions have the same denominator. Finally, one can subtract the numerators of the two fractions.

2. Factoring and Least common denominator
