If sqrt x=-7 then x=-49true or false

False.

IF √x = -7.

Square both sides

(√x)² = (-7)²

x = (-7)(-7)

x = 49

x will equal 49

False is your answer

hope this helps

29 is the correct answer

step-by-step explanation:

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.
