Answer:
Width: 6
Length: 20
Step-by-step explanation:
So the area of a rectangle can be defined as: where w=width and l=length.
In this case we don't know what the length is, so let's just say the length is the variable l, and since the width is 14 units less than the length, we can express it as (l-14). this gives us the equation: . We can solve for l, since we're given the area which is 120. So let's set the equation equal to that:
Original Equation:
Substitute 120 as A (given)
There is many ways to solve this equation: factoring, quadratic equation, completing the square etc... but in this case I'll just complete the square
Add (b/2)^2 to both sides to complete the square
Simplify
Rewrite right side a square binomial
Take the square root of both sides
Add 7 to both sides
to solve for width simply subtract 14 from the length which is 20, so the width is 6
Width: 6
L: 20
Answer: He was killed 24.83 hours before the body was found.
Step-by-step explanation:
Since we have given that
Here, T is the temperature of a body t hr after death, T = 82°F
T₀ is the air temperature , T₀ = 67°F
T₁ is the body temperature at the time of death = T₁ = 98.6°F
So, we will substitute all the values in the above equation.
Hence, he was killed 24.83 hours before the body was found.
