The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!
Answer:
This is the answer
Step-by-step explanation:
Answer:
The temperature of metal after five years = -18.96875
Step-by-step explanation:
Given : Function 
where x is measured in hours
Another function is added h(x)=-x-3
therefore, the resultant function f(x)=h(x)+c(x)

For x=5



Therefore, The temperature of metal after five years = -18.96875
