The restrictions are what the denominator can not be. The denominator cannot be zero. So if the denominator has x+1 in it. If you put -1 in place of x. You would get zero. -1 is a restriction

Emma wants to build a fence around the perimeter of her lawn. Each foot of fence costs $2. The rectangular lawn has an area of 3

AlladinOne [14]

Answer:

$\$160$

Step-by-step explanation:

To find the cost of the entire fence, we need to first determine the lawn's length before calculating its perimeter.

Area of rectangular lawn = $lw$ (formula for the area of a rectangle)

$364=14l$

$l=26$ feet

Now that we have the lawn's length and width, we can calculate the perimeter:

Perimeter $= 2l+2w$ (formula for the perimeter of a rectangle)

$=2(26)+2(14)$

$=80$ feet

Since each foot of lawn costs $2, then the cost of the entire fence will be:

$80\times2 = \$160$

∴ The entire fence costs $\$160$ .

Hope this helps :)

What is the sum of all even numbers 0-175 in algebraic form? If n49=99

Mila [183]

Answer:

$S_{88}=7656$

Step-by-step explanation:

We want to find the sum of all even numbers from 0 to 175.

The series will be:

$0+2+4+6+...+174$

The explicit formula for this is $a_n=2n-2$ , where $n\ge1$ .

We need to find how many terms are there.

$2n-2=174$

$2n=176\\n=88$

The sum of terms is given by:

$S_n=\frac{n}{2}(a_1+l)$

Substitute n=88, $a_1=0$ and l=174 to get:

$S_{88}=\frac{88}{2}(0+174)\\S_{88}=44*174\\S_{88}=7656$
