: A.
Is (square root x)^2=x an identity (true for all nonnegitive values of x)?
please explain answer
B. For the equation x-2sqrtx=0, perform the following:
solve for all values of x that satisfies the equation
answer & show work
C. graph the functions y=x and y=2 sqrt x on the same graph as B.(by plotting points if necessary) Show the points of intersection of these two graphs.
Also could you look at this? I think I have it right but I wanna double check
A right triangle is a triangle with one angle measuring 90 degrees. In a right triangle, the sides are related by Pythagorean Theorem, c^2=a^2+b^2, where c is the hypotenuse (the side opposite the 90 degree angle). Find the hypotenuse when the other two sides' measurements are 6 feet and 8 feet.
so heres what I have:
c^2=6^+8^2
c^2=36+64
sqrt c^2= sqrt 100 c= 5 sqrt 4 This question is from textbook College Algebra
