Someone please help me with these. I forgot how to do these. Need within a hour

looks to me that compare the two shapes and rell they why they are the same and if they dont look exacly the same then you put what is missing like for number 14 the side lengths are teaching so no side measurements are needed but circle the 2 lines because that is what shows they are congruent then for number 16 the box at the tip of the triangle is what shows the angle in degrees aren't the same  can you handle that?

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.

you can't solve x because it is 2 linear equation and you only have one equation
