(X-10)(X-10)
You need to first multiply out the brackets. So, first times X by X, which makes x^2 . Then do -10 x -10 which makes 100. You then need to multiply the X within the first bracket with the minus 10 in the second bracket which makes -10x. Do the same but with the -10 from the first bracket and the X from the second which again makes -10x. So altogether you have x^2-10x-10x+100. This can be simplified down to x^2-20x+100. You then do the same thing for the second question :)
100,000,000+70,000,000+6,000,000+ 900,000+40,000+5,000+500+90+6= 176,945,596

- Product rule with radicals: √ab = √a × √b
Using the product rule, simplify the radical as such:
√315 = √7 × √45 = √7 × √9 × √5 = 3 × √7 × √5 = 3√35
<u>The simplified radical of √315 is 3√35.</u>
To calculate 65 of 440, we solve the problem by using the following formula: (X*Y)/100 where X=65 and Y=440.
Thus, when we enter 65 and 440 into our formula, we get this:
(65*440)/100 = answer
First we multiplied 65 by 440 and then we divided that by 100. When we did this, we found the answer to be 286.
Therefore, 65 percent of 440 is 286.
The answer is 3.92.
Hope this helps!
