x = √(2-x)
x2 = 2-x
x2 + x = 2
x2 + x - 2 = 0
(x+2)(x-1) = 0
x = 1 or -2
Unfortunately, 2 over 2 minus 1 equals 5 over 6 is just a wrong answer! If it is 2 over 2, minus 1, the answer is that it equals zero. If it is 2, over 2 minus 1, the answer is that it equals 2.
Its just 462-205= 257
minus 21 think of it as 12+9 which equals 21 then just whack a minus sign infront
Take 8 minus 3 and that equals 5. Just act like the percent symbol isn't there.
5. Just do 9 minus 4. 5 plus 4 equals 9
If you have negetive 7 and you multiply it by 3 you are just adding negetive 7 three times so it remains negetive
The rule in differentiating any bracket is: The power of the bracket multiplied by the bracket itself but lowered by one degree, then multiplied by the derivative of whatever inside the bracket. Its easy, just remember it this way. y=(1-x^3)^3 y'= 3(1-x^3)^2(-3x^2)= -9x^2(1-x^3)^2
It is asking you to prove that you are a human, not a macro or bot trying to spam them with messages. Just do that math, and enter the number. In this case, the answer is 19.
47/100 times 109/1 equals 5123/100 equals 51.23 then you just subtract 109 minus 51.23 So the answer is 57.77.
zero, one half equals five tenths, just as 4/8 and 2/4
the answer is one (1) couldnt you have just used a calculator?!?
4800 you can just multiply 150x32
