Evaluate <br> a<br> +<br> 4<br> a+4a, plus, 4 when <br> a<br> =<br> 7<br> a=7a, equals, 7.

Scilla [17]

<em>When evaluating $a=7$ then we get that the expression is 11</em>

<h2>Explanation:</h2>

As I understand the expression is the following:

$a+4$

Let's call, that expression as $E$

So we are asked to find the value of the expression when $a=7$ . In other words, we need to substitute $a=7$ , so:

$E(7)=(7)+4 \\ \\ E(7)=11$

So <em>when evaluating $a=7$ then we get that the expression is 11</em>

The area of a square patio is 225 square feet. What is the perimeter of the patio

Liula [17]

STEP 1:
find the length of the sides of the square

AREA FORMULA (for a square)
x= side

A=x^2

225=x^2
take square root of both sides

15 feet= x

STEP 2:
find perimeter

PERIMETER FORMULA (for a square)

x= side of square

P= 4x
use x value from step 1

P= 4(15 ft)
P= 60 feet

ANSWER: The perimeter is 60 feet.

Hope this helps! :)
