2x2 + x2 = 3x2
Only if x is equal to 2.
x2 + x2 = 2x2 2x^2
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
0
It equals x2 - 34
2x2 + x2 = 3x2
Only if x is equal to 2.
(12x6)x2 = 12x8
Any monomial in the format: axn has a derivative equal to: nax(n - 1) In this case, "a" is equal to 1 and "n" is equal to 2. So the derivative of x2 is equal to 2x.
2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
x2 + x2 = 2x2 2x^2
You can combine like variables but not unlike variables.So, for example, x2 * x2 = x4 but x2 * y2 does not equal xy4!Let's make x equal 2 and y equal 3 just to demonstrate this.So if x2 * x2 = x4 then 22 * 22 = 24 which would mean 4 * 4 = 16 (Yes, that's right)But x2 * y2 can not be combined. 22 * 32 = 4 * 9 = 36 (which is not equal to a combination of x and y to the power 4).
x = x, y=y, x2=x2
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
