Answer: The amount of fencing needed can be expressed as 6x + 6 ft and, the cost of fencing can be expressed as Cost = 18x + 18
Step-by-step explanation: The dimensions of the rectangular garden are given as
Length = 2x + 3
Width = x
The amount of fencing that he would need is simply the total measurement all around the rectangular garden, that is, the perimeter. The perimeter of a rectangle is given as follows;
Perimeter = 2(L + W)
With the dimensions already provided we can now substitute for the values
Perimeter = 2(2x + 3 + x)
Perimeter = 2(3x + 3)
Perimeter = 6x + 6
Therefore the amount of fencing needed can be written out as,
6x + 6 ft
If however, fencing costs $3 per foot, then the cost of the entire fencing can be expressed as
Cost = 3(6x + 6)
Cost = 18x + 18
Answer:
Step-by-step explanation:
<u>Given expression:</u>
<h3>= 2(4f + 2g)</h3>
Distribute 2 to both terms.
<h3>= 8f + 4g</h3>
We can also split 8f into 4f and 4f.
<h3>= 4f + 4f + 4g</h3>
If we take 4 common
= 4(f + f + g)
<h3>= 4(2f + g)</h3>
