Answer:
x=0.996
Step-by-step explanation:
To take natural log ln , we need to get e^2x alone
Subtract 5 on both sides
Now we divide both sides by 3
Now we take 'ln' on both sides
As per log property we can move exponent 2x before ln
The value of ln(e) = 1
Divide both sides by 2
x= 0.996215082
Round to nearest thousandth
x=0.996
We have two widths of the same length plus one length
Let the width be
and the length be 
Perimeter = 2×width + 2×length
(equation 1)
The cost is $5 per foot on the width and $25 per foot on the length
Total cost = (5 × 2 × width) + (25 × length)
(equation 2)
We have two variables that we need to solve, so we will need to use the simultaneous equations method (either elimination or substitution)
Since equation 1 is given
, we can rearrange the equation to make the subject
then substitute this into equation 2
Substitute w = 75 back into 190 = w + l
190 = 75 + l
l = 190 - 75
l = 115
Answer:
Length = 115 feet
Width = 75 feet
Let the width be
Perimeter = 2×width + 2×length
The cost is $5 per foot on the width and $25 per foot on the length
Total cost = (5 × 2 × width) + (25 × length)
We have two variables that we need to solve, so we will need to use the simultaneous equations method (either elimination or substitution)
Since equation 1 is given
then substitute this into equation 2
Substitute w = 75 back into 190 = w + l
190 = 75 + l
l = 190 - 75
l = 115
Answer:
Length = 115 feet
Width = 75 feet
