When something says to 'rationalize the denominator,' when simplifying expressions with square roots, it is asking to get rid of any square roots in the denominator. This would put all of the square roots in the numerator, therefore only rational numbers would be in the denominator. We can rationalize the denominator by multiplying by the conjugate of the number in the denominator over itself (because that makes it a fraction equal to 1, and by multiplying by a fraction of 1, we don't change the value of the fraction).

You can put one figure inside of the other. The figure that is smaller will fit inside of the other figure. Both figures have congruent bases and the same height, so when you put the pyramid inside the prism, their bases overlap exactly. Since the shapes are the same height, the top of the pyramid touches the top of the prism. The pyramid clearly fits inside of the prism, so the volume of the pyramid must be smaller.
Hello :
2x² = 2
x²=1
x²-1=0
(x-1)(x+1) = 0
x-1=0 or x+1=0
x=1 or x= -1...(answer : <span>B. There are two solutions: -1 and 1 )</span>
