Equation for perimeter is 2L +2W
perimeter of the lot is 390 ft
so we have 390 = 2L +2w
divide all terms by 2:
195 = L + W
rewrite this as L = 195-W ( eq.1)
cost of fence for the length = 36 per foot so we have 36L
cost of fence for width = 6 per foot so we have 6W
the fence was 1 length and 2 sides
so we have 36l + 6w +6w = total cost
total cost is 4980
so we have 4980 = 36L + 6w +6w
combine like terms:
4980 = 36L +12w
replace L with eq1 from above:
4980 = 36(195-w) +12w
distribute:
4980 = 7020 -36w +12w
combine like terms:
4980 = 7020-24w
subtract 7020 from both sides:
-2040 = -24w
divide both sides by -24:
-2040 / -24 = 85
width = 85 feet
using eq1 L = 195 - 85
Length = 110 feet
lond = 110 feet
short = 85 feet
Answer:
.
Step-by-step explanation:
We have been given an expression and we are asked to simplify our given expression.
Using order of operations (PEMDAS) we will remove parenthesis first.
After removing parenthesis our expression will be,
After canceling out 1 with -1 we will get,
So our given expression simplifies to .
Let us write our expression in standard form. Since our expression is a polynomial and to write any polynomial in standard form, we write each term in order of degree, from highest to lowest, left to right.
Upon putting our polynomial into standard form we will get,
Therefore, after simplifying and putting our given expression in standard form we get our final expression as: .
1)
1 = 38
2 = 38
3 = 38
4 = 38
2)
1 = 32
2 = 90
3 = 58
4 = 32
Let me know if I'm wrong.
The answer is 34 m because if you add all of it together you get 34 m
