Abc is isosceles a=48 and b=4x+4 x=?

x=11

Step-by-step explanation:

=>4x+4=48

=>4x=48-4

=>x=44/4

=>x=11

207/8 is the right

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.
