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
If one bag weighs 5 1/4 ibs. Then it is 5 1/4 + (1/2)*(5 1/4) = 63/8 Ib or 7.875 Ib or 7/8
Answer:
2x + 8
Step-by-step explanation:
Don't worry, this is simple! Add up the common terms.
For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.
So combine the x terms: 2x
And the numerical terms: 8
Combine 2x and positive 8.
2x + 8
To find the discount, multiply 60 by .2, which is 12. Now subtract 12 from 60. The trousers should cost $48 now because the cost has been reduced by 20% of 60, which is $12.
