It's multily
f(x) time g(x) is basically what they wnat

so

(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)

Goshia [24]

Answer:

Step-by-step explanation:

The volume of this cylindrical vase is V = πr²h.  Substituting 3 in for r and 8 in for h, we get V = π(3 in)²(8 in), or 72π in³.

We'll need to pour 72π in³ of water into the vase.

Given that a*b = 2ab - 3b. Determine 2*(3*5)​
Oksanka [162]

Answer:

15

Problem:

Given that a*b = 2ab - 3b. Determine 2*(3*5)​

Step-by-step explanation:

First we find 3*5 using rule a*b = 2ab - 3b.

3*5=2(3)(5)-3(5)

3*5=30-15

3*5=15

Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.

2*15=2(2)(15)-3(15)

2*15=60-45

2*15=15

Therefore, 2*(3*5)=15.

What is -1.1 repeating as a fraction
Thepotemich [5.8K]

Hey \\ There!

\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11   \\ \\ 1(10)= 10 \\ \\ \\  Fraction:  \frac{-11}{10} this is also equal to: -1\frac{1}{10}

Your answer would probably be: \frac{-11}{10} =  -1\frac{1}{10}

Good luck on your assignment and enjoy your day!
