30/5= 6
6 - 2 = 4
Your number is four
It would be -6. -4-6 is -10
Answer:
Factor {x}^{2}-4x-5x
2
−4x−5.
(x-5)(x+1)=0(x−5)(x+1)=0
2 Solve for x.
x=5,-1x=5,−1
Step-by-step explanation:
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
Answer:
1/7
Step-by-step explanation:
there are 7 number possibilities 0,1,2,3,4,5,6.
so if they each have an equal probability the answer is 1/7
