A)
you square both sides
by squaring the left side, you get rid of the square root leaving only x one that side. But you also need to square the other side because whatever you do to one side you have to do to the other.
Answer: x=o/a^2
b)
To get o on its own on one side you multiply a. You basically do the opposite of what a originally does to cancel it out. So originally, a is dividing o so if you do the opposite, a will multiply on both sides.
a X o cancels out the a, leaving only o.
But whatever you do to one side, you have to do to the other. so Vx (square root of x) has to also be multiplied by a.
Answer: Vx X a=o
c) this is basically the same as b).
apply what i said in b) to this and you will get your answer
to cancel out o, you multiply both sides by o.
because o is getting divided, you will have to do the opposite which is multiply o.
Answer: Vx X o=a
Answer: Yes
Step-by-step explanation: A rational number is a number that can be described as a fraction. -92 can be a fraction, therefor it's rational.
Answer:
X^2 -4
Step-by-step explanation:
Not entirely sure but would u just expand the brackets. As this is a difference between 2 squares the answer should be correct but it not sure.
Answer:
When squaring a fraction, square both numerator AND denominator
