Step-by-step explanation:
<span>5,286÷3
how many digits will the classroom number have
Notice that we have 4 digits as dividend with a place value of thousands as the
highest and to be divided with our divisor that have only 1 digit with a place value
of ones.
Now, let’s see how many digit will our quotient have:
=> 5 286 / 3
=> 1 762 is the quotient, it has still 4 digit with a place value of
thousands.
To check simply multiply our quotient and divisor.</span>

the answer is d
Step-by-step explanation:

Answer:
To know if the equation is true, you need to write it down on a piece of paper and see if you get the results.
Step-by-step explanation:
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6
Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3
Set each equal to 0;
z = -6
z + 6 = 0
z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.
