hello :
<span>14ax-y+2ay-7x = (14ax+2ay) +(-y -7x) = 2a(7x+y) - (7x+y)
</span>14ax-y+2ay-7x = (7x+y)(2a - 1)
B. A unit rate always has the number 1 as the second term.
6) D , 7) A, 8) 8) C
Step-by-step explanation:
(7×7)+(4×4)=65
√65
=8
P(B given A) = P(A and B) / P(A)
P(B given A) = 0.10 / 0.20
P(B given A) = 0.50
