so x squared + 12 = 0 so xsquared = -12 which lands you in the realm of imaginary numbers. The square root of -12 is 2i root 3 where i is the imaginary sqrt of -1.
Because: (9-x)(9-x) = 81-18x+x^2
x2 + y2 isn't an equation. Until you say it's equal to something, it's just anexpression, and its numerical value depends on the values of 'x' and 'y'.If you say that the expression is equal to some number, the it's the equationof a circle, with its center at the origin, and a radius equal to the square rootof the number.
(x + 4)(x + 1)
In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared
y=xsquared-4x+2
so x squared + 12 = 0 so xsquared = -12 which lands you in the realm of imaginary numbers. The square root of -12 is 2i root 3 where i is the imaginary sqrt of -1.

Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.

Dire.
X + y
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
The value of X after simplifying fully xsquared -16 3xsquared plus 10x -8 is either 2 or 4.
(x + 4)(x + 1)
No.
