Answer:
(x+4)(x+1)(2x-1)
Step-by-step explanation:
factors should have minus sign
so
(x+4)(x+1)(2x-1)
Answer:
Step-by-step explanation:
We are given the expression, 
On simplifying, we have,
i.e. 
Now, we will rationalize the expression,
i.e. 
i.e. 
i.e. 
Since, 
, we get,
i.e. 
i.e.
So, the simplified expression is .
The length would be 16, the width would be 9

Answer: 0.3
Step-by-step explanation:
From the question,
A used car dealer sells SUVs and cars. Of all the vehicles, 70% are cars. Since 70% are cars, SUV will be (100% - 70%) = 30%. Of all the vehicles, 10% are black SUVs. To calculate the probability than an SUV chosen is black goes thus:
P(A|B) = P(A and B) / P(B)
P(SUV | black) = P(SUV and black) / P(suv)
P(suv | black) = 10%/ 30%
P(suv | black) = 0.1/0.3
P(suv | black) = 0.3
