Step-by-step explanation:
Answer:6=C 7=C
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
The probability that the two socks match can be translated into the probability of getting two blue socks or two grey socks.
The combination ways for taking 2 socks from 16 socks would be: 16C2= 16!/2!14!= 120
Way to get 2 blue socks of 6 blue sock: 6C2= 6!/2!4!= 15
Way to get 2 grey socks of 10 grey sock: 10C2= 10!/2!8!= 45
Then the probability is: 15+45/ 120= 60/120= 1/2
Answer:
216 in2
Step-by-step explanation:
the area of the rectangle is
20(12)=240
area of the triangle is
4(6)= 24
so now we subtract, 240-24= 216 in2
