(7x+2)(20-3x/4) = 140x + 40 - 21x²/4 - 3x/2 = -21/4 x² + 138 1/2 x + 40
this is one of those multiplications that doesn't make the result look any simpler...
First off, we need to find how much would a people need,by dividing the amount needed.
The equation of how much a people would need:
55÷33
=1.67 or 55/33 (it would be best to keep it in fraction to get a more precise answer)
To find out how much 2020 people need ,we would mutiply the answer above by 2020:
55/33×2020
≈3366.7
≈3367
Thus,you would have to prepare 3367 can of soup.
hope it helps!
Answer: x =42°
The angles are equal
We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.
