Calculus

1,760 × 8,800 = 15,488,000. You can easily arrive at this result, if you like, through mental calculations: First, of all, 1760 × 8800 = 176 × 88 × 1,000 = 2 × 88 × 88 × 1,000. Now, what is a painless way to find 88² ? 88² - 12² = (88 - 12)(88 + 12) = 76 × 100 = 7,600. Thus, 88² = 7,600 + 12² = 7,744. Now, double 7,744, and add 3 zeroes. Magically, you get 15,488,000, which is your answer. After all, 2(7,500 + 244) = 15,000 + 488. You can easily confirm this with your calculator.

3+2 is a pair cause it has equled to 6.

x = 392 I found this answer on a table that matches the first six numbers you have given.

y = 5x is the equation of a line. Subtitute any value for "x", then calculate the corresponding value of "y", which in this case is simply the value of "x" multipled by 5.

No.

its still 3x+x2

to add you must have same variable you would only be able to multiply these numbers to get 3x3 but they cannot be added

No because it's an algebraic expression that contains 3 terms.

simple. Set out the problem clearly:

-9 + 7x = -37.

Move the singular number over the equals sign, which makes itself opposite, in this case, the 9 is negative, and when moved over the equals sign, becomes positive.

7x= -37+9

7x= -28

x= -28/7

x = -4

The question contains only an incomplete expression, not an equation (or inequality). There is, therefore, nothing that can be solved.

the answer is x=8/5 and x=4/3 from: Scott Powell

(3x+4)(x-2)

3x2 -6x+4x-8

3x2-2x-8

99 x 25 = 2475

4x-y=2, therefore
y=4x-2

sub y into 3x+2y=6...
3x+8x-4=6
11x=10
x=10/11

Im guessing by counting numerals youmean integers, and that you are asking, what are the divisors of 60.

And this isn't really calculus.

60 = 2x30=3x20=4x15=5x12=6x10 and then if you want negative values as well then there are all the same with a negative sign in front of them. i guess if you wanted to be clever you could also have everything with one negative and i in front of both of them to....

so that gives you an answer of 10, 20 or 40 depending on your question.

False.
