Calculate the dealer's cost of a new car if the base price is $26,995 and the options package is $2000. The dealer's cost is 85% of the base price and 70% of the options.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.

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.

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
