Step-by-step explanation:
Answer:
290 in^2
Step-by-step explanation:
So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.
The length=5. The width=5. The height=12.
You put those numbers into the formula.
2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.
I think u need to subtract both up and both down
Let the actor's initial weight be 'x'
He is then gaining 20 pounds. The clue is in the word 'gaining' as it means 'increasing' or in Mathematics can be related as 'plus'
The expression is: x+20
He then loses 15 pounds. The clue is in the word 'losses' as it means 15 pounds is to be subtracted from the last value
Last value is x + 20
The weight now is x + 20 - 15 = x + 5
Length =l
Height = h
Area function = l * h = 924
Perimeter function = 2i + 2h = 122
Divide by 2
I + h = 61.
Plug in I or h for the other variable
I * (61 - I) = 924
61i - i^2 = 924
Factor the function
(-I + 28)(I - 33) = 0
l = 33 as l cannot be negative
61 - 33 = 28
h = 28
Difference between h and l is 33-28=5
