Answer: use x+4 to divide x³+2x²-23x-60
x² -2x-15
__________
x+4 √x³+2x²-23x-60
-(x³+4x²)
-2x²-23x-60
-(-2x²-8x)
-15x-60
-(-15x-60)
Factorize x²-2x-15
x²-5x+3x-15
x(x-5)+3(x-5)
(x-5)(x+3)
Step-by-step explanation:
Answer:
Answer is 2a + 8 because 2 times a is 2a and 2 times 4 is 8
Answer:
1.178511301978
Step-by-step explanation:
Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
