The expression can be simplified by subtracting the terms.
2-3=-1
The final answer is -1.
Yes, they are independent because P(A) ⋅ P(B) = P(A ∩ B)
Answer:
x=-7, x=-8
Step-by-step explanation:
x^2 +15x +56=0
look for two numbers that their sum is 15 and their product =56
(x+7)(x+8)=0
x=-7, x=-8
Answer:
(x+a) (x+b)=x(x+b)+a(x+b)=x²+bx+ax+ab=x²+x(a+b)+ab
1.
<span>1.5x-1 > 6.5
1.5x>1+6.5
</span>1.5x>7.5, divide by 1.5
x>5, is represented by the region to the right of the vertical line x=5
2.
<span>7x+3 < -25
7x<-25-3
7x<-28, divide by 4:
x<-4
</span>x<-4, is represented by the region to the left of the vertical line x=-4
