Note that c is the hypotenuse of the blue triangle, and that the Pyth. Thm. states that (length of one leg)^2 + (length of the other leg)^2 = (hyp)^2.
Therefore, (hyp)^2 = c^2 = [2sqrt(x^2+3x)]^2 + 3^2, or
= 4(x^2+3x) + 9, or
= 4x^2 + 12x + 9 = (2x+3)^2
Taking the sqrt of both sides, c = plus or minus (2x+3). Eliminate -(2x+3) because the middle term of the square of this would be negative, in conflict with the given +12x.
c=2x+3 is the correct answer.
Answer: 3
90 pages in 30 minutes so divide 90 by 30 and 90 divided 30 = 3
Hope this helps!
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!
I am not 100% positive but I think it is 4117.66
