Explain how you can mentally find 8 times 45 by using distributive property. and explain

Very handy question. Don't use a calculator. That's "cheating" when you do problems like this.

Most people would break up 45 into something more easily handled but I think there is an easier way to do it. All you have to know is what 2 * 45 is.

Do you know that 2 * 45 = 90?

If you do then here's a much easier way to do the problem.

45 ( 10 - 2)

45* 10 = 450

45 * 2 = 90

450 - 90 = 360

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

m a t h w a y. c o m
