Answer:
90, there are 32 ninetys in 32 X 90 and there are 33 ninetys in 33 X 90, meaning there is one more 90 in 33 X 90 than 32 X 90
The answer to b is 24×600=14400
24=hours in a day
600=blooded pumped per hour
14400=the amount the blood is pumped a day
For this case we must write in algebraic symbology the expression described above:
We have an equation, then:
- x squared plus y squared:

- minus 2x plus 7y plus 1:

- equals zero:

We construct the equation:
