2x^2+3
x=3
2(3)^2+3
2(9)+3

21 is the answer.
Answer:
The length is 13 feet and the width is 5 feet
Step-by-step explanation:
Let w represent the width
Since the length is 3 more than twice the width, it can be represented by 2w + 3
Using this, set up an equation and solve for w:
w + (2w + 3) = 18
3w + 3 = 18
3w = 15
w = 5
So, the width is 5
Use 2w + 3 to find the length:
2w + 3
2(5) + 3
= 13
The length is 13 feet and the width is 5 feet
2 - 5x = -13
-2 -2
---------------
-5x = -15
/-5 /-5
-------------
x = 3
Hope this helps!
