Answer:
14 is the simplified answer, but the whole answer is 17 + -18/6
Step-by-step explanation:
Divide
−
18 by 6. h (−18) = 17 − 3 Subtract 3 from 17. h (−18)= 14
The final answer is 14.
Answer:
Initially, you have 2573 pieces.
You use 5 pieces each minute.
Right when you start, you have 2573 pieces.
One minute after that, you have 2573 - 5 pieces.
Another minute after, you have 2573 - 2*5 pieces.
Another minute after, you have 2573 - 3*5 pieces.
And so on.
You can see the pattern here, and with this, we can find the linear equation that represents the number of pieces that you have as a function of time.
Then, if the variable t represents the number of minutes that passed since you started, we can write the equation:
f(t) = 2573 - 5*t
That represents the number of pieces that you have after t minutes.
I think it’s square because there is a cross section on the two sides of the square that are parallel to each other :)
