Answer:
———————
6.75 feet |
———————
Step-by-step explanation:
Let the width be x. If the width is x, the the length has to be 3x because in the question it says that the length is 3 times the width.
Since this is a rectangle, the opposite side has the same measure, like in the attachment below.
To find the perimeter, you would add up all the sides.
3x+3x+x+x
=6x+2x
=8x
It is also given in the question that he uses 18 feet. Which means that the perimeter is 18 feet. But you figured out that 8x is ALSO the perimeter. This means that you can say: 8x=18.
Solve for x, 18/8=9/4=2.25.
You want the length, which is 3x. So 3(2.25) is your answer.
3(2.25) = 6.75
Step-by-step explanation:
Add 9 to both sides of the equation.
if you want to create a trinomial square on the left, find value that is equal to the square of half of b
Add the term to each side of the equation
SIMPLIFY >:(
How to Simplify it:
-Raise the -2 to the power of 2
and ten simplify 9 + (-2)^2 :
--Raise -2 to the power of 2 and then add 9 and 4
Factor the perfect trinomial square into (x - 2)^2
Solve the equation for x
How to do it:
-Take the square root of each side of the equation to set up the solution for x
--Then remove the perfect root factor, x - 2 under the radical to solve for x
---Remove parenthesis
----add 2 to both sides of the equation.
the final answer could be shown in different ways,but the exact form is x=±√13+2
In decimal form its x=5.60555127…,−1.60555127…
