Do not understand please help <br> Thank u

Answer:

43.4

Step-by-step explanation:

You will need to use the phythagoream therom, which is a² + b² = c².  Plug the values in for the variables to get 7² + b² = 44², (c would equal the hypothenuse because the hypothenuse is the longest side of the triangle.)  Square the values to get 49 + b² = 1936.  Subtract 49 from both sides to get b² = 1887, then take the square root of both sides to get b = 43.4 (rounded to the nearest tenth.)  

I am really sorry if I'm wrong, but have a good day/night!  :)

(-1 - 3i)(-1 + 3i) = 1 - 3i + 3i -9i²

1 - 9i²; i² = -1, therefore 1 - 9(-1) = 1 + 9 = 10

Corey bought 112 feet of porch boards at the lumberyard. If each foot cost $1.59,how much change would he get back from $200?
abruzzese [7]
So first you want to do the cost of each foot times the number of feet 112 * $1.59 = $178.08

Then do the subtraction $200.00 - $178.08 = $21.92

Therefore, the answer is C
