Answer:

Step-by-step explanation:

So timing a fraction with a fraction smaller by 1 means its a proper fraction.

And it can't get bigger than it already is because it's timing a less than 1 itself.

So it's A, it will be smaller

Paul is growing a rectangular rose garden. His area is 5x2+ 8x +3. What are the dimensions of his rectangle?

irina [24]

Answer:

$Length = 5x + 3$

$Width = x +1$

Step-by-step explanation:

Given

$Area = 5x^2 + 8x + 3$

Required

Determine the dimensions

To do this, we simply factorize the given expression.

$Area = 5x^2 + 8x + 3$

Expand

$Area = 5x^2 + 5x +3x+ 3$

Factorize

$Area = 5x(x + 1) +3(x+ 1)$

Factor out x + 1

$Area = (5x +3) (x+ 1)$

Area is calculated as:

$Area = Length * Width$

So:

$Length = 5x + 3$

$Width = x +1$

Work out an expression for the nth term for this sequence:<br><br> 23,35,47,49

notsponge [240]

<h3>Answer:</h3>

$a_n = 23 +12(n -1)$

<h3>Explanation:</h3>

The $n$ th term of an arithmetic sequence is explicitly defined as $a_n = a_1 +d(n -1)$ where $a_1$ is the first term of the sequence and $d$ is the the common difference.

From the given first five terms of the sequence we can see that the first term is $23$ so $a_1 = 23$ .

The common difference, $d$ , can be calculated by $a_n - a_{n -1}$ so we'll find the common difference of the given sequence by letting $n = 2$

$d = a_2 - a_{2 -1} \\d = a_2 -a_{1} \\d = 35 -23 \\ d = 12$ .

Now let's plug everything we know.

$a_1 = 23$

$d = 12$

$a_n = 23 + 12(n -1)$

How to find the volume of a rectangular prism

Ann [662]

To find the volume of a rectangle prism, you will need to use the formula V= lenght * width * height. Make sure you state your answer in cubic units.
For example you have a rectangle prism with a lenght of 15m, width 8m, and a hieght of 12m.
V = l * w * h
V = 15 * 8 * 12
V= 120 * 12
V= 1,440
V= 1,440m^3

I hope this help.
