Answer:
5/4
Step-by-step explanation:
y increases by 5 for every 4 increase of x.
Answer:
Step 1:
Addition is commutative
A + B = B + A
So the terms can be rearranged
Step 4:
2x(2x - 3) + 5(2x - 3)
Since (2x - 3) is common to both terms,
You can take it common
(2x - 3)(2x + 5)
This can be proved verified using distribution property
(2x - 3)(2x + 5) is the same as
(2x + 5)(2x - 3) because multiplication is commutative
Probability of picking a green ball = number of green balls / total number of balls
Pr(green) = 4/(3+4+2+6) = 4/15
