Describe or show two ways to find the following product: 1 1/3x 2.

Alenkasestr [34]

1 and 1/3 time 2? i thinks that's what you want?

or is it 1/3x squared?

I;ll presume its 1 and 1/3 time 2

first way:

Multiple whole numbers first 1 x 2 = 2

Multiple fraction by the two 1/3 x 2 = 2/3

now add them together

2 and 2/3

second way

Make 1 and 1/3 improper = 4/3

make 2 into a a/b form = 2/1

now 4/3 x 2/1 = 8/3 now make a mixed number 2 and 2/3

Let x represent the side length of the squares.

We have been given that an open box is made from an 8 by ten-inch rectangular piece of cardboard by cutting squares from each corner and folding up the sides. We are asked to find the volume of the box.

The side of box will be $8-x-x=8-2x$ and $10-x-x=10-2x$ .

The height of the box will be $x$ .

The volume of box will be area of base times height.

$\text{Volume of box}=(8-2x)(10-2x)\cdot x$

Now we will use FOIL to simplify our expression.

$\text{Volume of box}=(80-16x-20x+4x^2)\cdot x$

$\text{Volume of box}=(80-36x+4x^2)\cdot x$

Now we will distribute x.

$\text{Volume of box}=80x-36x^2+4x^3$

$V(x)=80x-36x^2+4x^3$

Therefore, the volume of the box would be $V(x)=80x-36x^2+4x^3$ .

The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?

Sidana [21]

<h3><u>Answer:</u></h3>

x = 7.2

<h3><u>Step-by-step explanation:</u></h3>

Perimeter: Side 1 + Side 2 + Side 3

=> x + 4 + 3x + 7 + x + 9 = 56

=> 5x + 20 = 56

=> 5x = 56 - 20

=> 5x = 36

=> x = 7.2

<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.

Hoped this helped.
