What is the simplest form of the radical expression?

- (7 + √10) / 3.

Step-by-step explanation:

You simplify this by multiplying the numerator and denominator by the conjugate of the denominator which, in this case, is √2 + √5.

(√2 + √5)(√2 + √5)         2 + 2√10 + 5            7 + 2√10

=     =        

(√2 - √5)(√2 + √5)                 2 - 5                        -3

Answer is - (7 + √10) / 3.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
