How do i solve this equation
a=2x+6xz

If im not wrong the answer for this question is x=A/2+6z.
First you take the x out, so you will get x(2+6z).
Then move it to the other side as you want to find x. And it will look like the answer above. You can recheck later.

It will cost $540i think

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
