Answer:

b = -6.307 or -11.693

Step-by-step explanation:

b^{2} +9b +13\\

This can't be factored so you need to use the quadratic formula which is

-b ± \frac{\sqrt{b^{2} -4ac}}{2a}

Plugging the numbers from the equation in, it's

-(9) ± \frac{\sqrt{(9)^{2}-4(1)(13) } }{2(1)}

This simplifies down to b = -6.307 or -11.693.

These are both real solutions.

Let U be a universal set with subsets A and B such that n(U)=118, n(A)=57, n(B′)=69, and n(A∩B)=11. Find the following:
Arturiano [62]
n(B)=n(U)-n(B')=118-69=49\\
n(A\cup B)=n(A)+n(B)-n(A\cap B)=57+49-11=95\\
n((A\cap B)')=n(U)-n(A\cap B)=118-11=107
