The first ten positive integer multiples of 45 are as follows: 1 x 45 = 45 2 x 45 = 90 3 x 45 = 135 4 x 45 = 180 5 x 45 = 225 6 x 45 = 270 7 x 45 = 315 8 x 45 = 360 9 x 45 = 405 10 x 45 = 450
Since you are using a computer you have access to a calculator: click [START] - click [RUN] - type "calc" - hit [ENTER] Answer: √45 + √80 = √245 √45 = 6.7082 √80 = 8.9443 6.7082 + 8.9443 = 15.6525 Or, √45 + √80 = √(5 x 9) + √(5 x 16) = √5 x √9 + √5 x √16 = 3√5 + 4√5 = 7√5
X-45=12 ________ +45 +45 ________ x= 57
When what equals 9: the 45/x, the 45, or the x? In the case of 45/x = 9, 45/x = 9. In the case of x = 9, 45/x = 5. In the case of 45 = 9, the case of a false statement is being considered, and therefore 45/x is undefined.
