Fast find a simplified expression to represent the area of the triangle. the area formula for a triangle is bh, where b is the base and h is the height. the expression that represents the area of this triangle is x2 + x + cm2.

1) 4    2) 22     3) -12

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.
