12. The vertices of AFGH are F(2,1), (4,1), and H[4,-1). The vertices of the image of the triangle after a dilation centered at (0,0) are F(4,2), G'48,2), and H'(8,-2). What is the scale factor of the dilation?

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

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.

investment b is an ordinary annuity with $3,909.64 in the account after one year.
