Answer:

I saw an answer for this one and saw it was incorrect

Step-by-step explanation:

5x + 2 = 12

5x = 12 - 2 ( moved the constant to the right )

5x = 10 ( both sided needed to be divided by 5 )

x = 2

The glass fish tank does not have a cover. Find the total area of the glass panels used to make the tank.

pogonyaev

You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504

Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.

Answer:

$x^3+3x^2+2x$

Step-by-step explanation:

<u>Definitions</u>

Integer: A whole number that can be positive, negative, or zero.

Consecutive Integers: Integers that follow each other continuously in the order from smallest to largest.

Product: The result of multiplying two of more values together.

Let x be the first integer.

Therefore, to find the consecutive integers, add 1 to each term:

x
x + 1
(x + 1) + 1 = x + 2

Therefore, the product of the first three consecutive integers is:

$\begin{aligned}x(x+1)(x+2) & = (x \cdot x+x \cdot 1)(x+2)\\& = (x^2+x)(x+2)\\ & = x^2 \cdot x+x^2 \cdot 2+x \cdot x+x \cdot 2\\& = x^3+2x^2+x^2+2x\\& = x^3+3x^2+2x\end{aligned}$
