Answer:
Total amount of fencing needed as an algebraic expression in terms of x is: <em>10x</em><em> </em><em>+</em><em> </em><em>3</em> .
Step-by-step explanation:
As it is given that each rectangle has the same dimensions, the dimensions of each rectangle must be: x units by 2x + 1 units.
Based on this, we can calculate the total amount of fencing needed.
Let width of each rectangle = x
Let length of each rectangle = 2x + 1
There are 4 widths and 3 lengths in total of fencing.
Therefore:
= 4 ( x ) + 3 ( 2x + 1 )
Expand:
= 4x + 6x + 3
Group like-terms:
= 10x + 3
2x+10, multiply to two each term x and 5
<u>The number is -1</u>
-
Steps:
2x + 7 = x + 6 (Sum of twice a number and 7 is equal to sum of the number and 6.)
2x = x - 1 (Subtracted 7 from both sides.)
x = -1 (Subtracted x from both sides.)

Hope this helped :)
