Answer:
C) 12/20
Step-by-step explanation:
Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).
So the probability is:
(10 + 4 − 2) / 20 = 12/20.
(2p + 7)(3p-9)
2p x 3p= 6p^2
2p x -9= -18p
7 x 3p=21p
7 x -9=-63
6p^2 - 18p + 21p - 63
6p^2 + 3p -63 is the answer.
