i believe it is the second option
-15 is already rational itself, but it as a fraction:
-15/1
Answer:
The light blue one -- second from the left.
x = 14 ; y = 7√2
Step-by-step explanation:
This is a right triangle. One of the angles is 45. So is the other base angle.
So one of the legs is 7√2. The other leg is also 7√2 because they are opposite equal angles.
The hypotenuse is
a^2 + b^2 = c^2
a = b
2a^2 = c^2
2 (7√2)² = c^2
2 49 * 2 = c^2
4 * 49 = c^2
c^2 = 196
c = 14
Answer: A. (k o p) (x)=2x^2-16x+24
You welcome.
I think #3 is 20 and #4 is a trapezoid. im so sorry if that’s wrong. if it is lmk and ill try again.
