Answer:

Step-by-step explanation:
Given



Required
Determine the overall change
The overall change is calculated by adding all increments and subtract the decrement.
This is done as follows;

Convert to Improper Fraction

Take LCM


Convert to mixed number

<em>Hence; the overall change is an increment of </em>
<em></em>
If you would like to simplify <span>3j - {2k - [5h - (3j + k)]}, you can do this using the following steps:
</span>3j - {2k - [5h - (3j + k)]} = 3j - {2k - [5h - 3j - k]} = 3j - {2k - 5h + 3j + k} = <span>3j - 2k + 5h - 3j - k = - 3k + 5h = 5h - 3k
The correct result would be 5h - 3k.

Answer: E.) 41.95m
Step-by-step explanation:
Area (A) = 85 square meters
Length (L) = a
Width (W) = (a - 10) meters
Area of rectangle(A) = Length (L) × Width (W)
85 = a × (a - 10)
85 = a^2 - 10a
a^2 - 10a - 85 = 0
Using quadratic equation solver :
a = 15.488088482 or a = −5.488088482
Since a cannot be negative, a = 15.49m
Therefore, Length (L) = 15.488m
Width(W) = a - 10 = (15.488 - 10) = 5.488m
Perimeter of rectangle(P) :
P = 2 (L + W)
P = 2 (15.488 + 5.488)
P = 2(20.976)
P = 41.952m
P = 41.95m
