Use compatible numbers to find two estimates that the quotient is between 1045÷2

The two estimates of quotient is 522 and 523 .

Step-by-step explanation:

Compatible numbers are numbers which are close in value to the given numbers, and  make it easy to calculate the answer for any given arithmetic problem .

To find two estimates that the quotient is between in 1045÷2

We now that 1045 is greater than 1044 and less than 1046 i.e.1044<1045<1046

Dividing 2 from all sides ,we get

1044÷2<1045÷2<1046÷2

⇒522<1045÷2<523

As the quotient of 1045÷2 is lying between 522 and 523.

Therefore, the two estimates of quotient is 522 and 523

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

can you rephrase the question ? it is unclear : -)
