Answer:
=4x2+12x+9
hope it helps you!
Step-by-step explanation:
Use a proportion.
121/16.5 = 22/m
121m = 16.5 * 22
11m = 16.5 * 2
11m = 33
m = 3
3 minutes.
Answer:
e. 10√30
Step-by-step explanation:
In this right triangle geometry, all of the right triangles are similar. This means that the ratio of long side to hypotenuse is the same for all triangles:
x/(10+50) = 50/x
Multiplying by 60x, we have ...
x^2 = 3000
x = 10√30 . . . . . take the square root. Matches choice E.

<em>Comment on estimating</em>
You're looking for x. Examining the figure, you see that x is the long side of the triangle with hypotenuse 10+50=60, so it will be shorter than that value. x is also the hypotenuse of the triangle with long side 50. So, x will be longer than 50.
The only answer choice with a value between 50 and 60 is choice E.
You don't even need to know how to find x. You only need to know that the hypotenuse is the longest side in a right triangle.
If they EACH bough 2 of EACH size soda, then it would be.
S: # of different sized sodas
P: Price of soda
5×2(S×P)
but if each sized sodas cost a different amount it would be
S: Price of first size
S2: Price of second size
S3: Price of third size
and so on.
5×2(S+S2+S3...)
but if they all together bought 2 of EACH size soda, then it is.
2(S×P)
but if each sized sodas cost a different amount it would be
S: Price of first size
S2: Price of second size
S3: Price of third size
and so on.
2(S+S2+S3...)
