Answer:
i rlly dont want to make you wrong cause i feel lik im wrong but i got all of them as cant be sides of triangles
Step-by-step explanation:
i did use a calculator tho
Let

be the number of boxes the team brings with them. Their weight combined with the boxes can't exceed the capacity of 1400. Assuming the elevator runs fine at that exact weight, you want to find the number of boxes, each of which contributes 40 pounds. This is given by the equation

Solving for

, you have



So the team can bring *at most* 5 boxes at a time.
A whole number? ok. 24x10^4. usually though you would use standard form so it would be 2.4x10^5
Subtract 49 by its negative so now
x^2-16x=-49
then move -16 so
x^2=-49+16x
then add -49 and 16 so then you get
X^2+your answer)
then find the square root because this was in exponential form so find the square root of x^2 and of your answer so
X= Your answer
