the answer is -10 you just multiply 3 times -2 and then subract 4
Answer:
30
Step-by-step explanation:
triangle ABC is proportional to triangle BCD so
hypothenuse of ABC/ ajdacent of ABC = hypotrnus BCD/ ajdacent of BCD
in short
AC/BC = BC/DC
10/x = x/3
10 . 3 = x²
x² = 30
x = √30
so the question mark is 30
It is b. Y=8. Steps are in picture.
(y-7)(y+6)
Hopefully this is right :)
C. p-7 because 7 less than p implies that we would subtract 7 from p
