Answer:

6 books

15+ 15= 30

30+15=45

45+15=60

60+15=75

75+15=90

We see 15 6 times. 15 x 6= 90

                                90/6= 15

If a polynomial function f(x) has roots 3+Sqrt(5) and -6, what must be a factor of f(x)
neonofarm [45]

Answer:

The two factors of the given polynomial f(x) are (x - 3 -√5) and (x +6) .

Step-by-step explanation:

Here, the roots of the given polynomial f(x)  are

Root 1  =  3 + √5

and  Root 2   =  (-6)

Now,as we know that if x  = a is the root of the any given polynomial p(x), then the expression (x-a) is the FACTOR of the polynomial p(x).

Now, here root 1 : x  = 3 + √5

So, x  - (3 + √5 ) is the FACTOR of the f(x)

or, ( x - 3 -√5) is the   first factor of f(x).

Also, here root 2 : x  = (-6)

So, x  - (-6 )   = x + 6   is the FACTOR of the f(x)

or, ( x +6 ) is the second factor of f(x).

Hence, the two factors of the given polynomial f(x)

are ( x - 3 -√5) and  ( x +6 ) .

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cat
qwelly [4]

Answer:

147 cats

Step-by-step explanation

There are 3 dogs/ 7 cats

3x + 7x = 210

10x = 210

210 ÷ 10 = 21

Therefore,

x = 21.

dogs would be 3x (3 x 21) = 63

cats would be 7x (7 x 21) = 147
