b becuces you add the dived
Answer:
2 packs
Step-by-step explanation:
Since there is 10 packs just divided it by how many notebooks were in the pack.
It is a root of the polynomial if it causes the equation to equal 0.
Let's try each number.
Substituting -3 for x...
(-3)³ - 4(-3)² -11(-3) + 30
-27 - 36 + 33 + 30
0
Therefore, a. -3 is a root to our polynomial.
You could try the rest, but I won't waste time with it. None of the others are roots, and it's multiple choice which means usually just one answer.
Answer:
$1 is a missing due to the addition of unrelated amounts.
$(20 - 1)×3 + $2
Can never be equal to
$20 × 3
Step-by-step explanation:
The statement in a nut-shell is
- The three friends paid $20 each initially, to make $60.
- $1 each was returned to them, so that they reduced the expenses, and paid $19 each, to make $57.
- They tipped a man $2.
WHY IS $57 + $2 ≠ $60?
That was so, because the amounts that were added weren't related.
If their total spending was what they wanted to calculate, it should have included the amount in the receipt of $55 payment received from the hotel.
The right calculation should have been:
$55 payment to the hotel
+
$3 change the three friends received ($1 each)
+
$2 tip they gave.
=
$60
Ignore the last one!! But I hope this helps!! If you need an explanation you can message me!
