Answer:

4.3π or 13.51 = r

Step-by-step explanation:

C=2πr To find the circumference of a circle, you must have the formula

8.6π = 2πr      Substitute the C for 8.6π

4.3π = r           Divide both sides by 2π

13.51 = r         Simplify 4.3π if needed

Binomial (x - 6) and trinomial (-2x2 + x + 9) are the factors of which of the
djyliett [7]

Answer:

Option (3)

Step-by-step explanation:

If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.

(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)

                              = -2x³ + x² + 9x + 12x² - 6x - 54

                              = -2x³ + 13x² + 3x - 54

Therefore, Option (3) will be the correct option.

i need help with my math :( im horrable with it i cant do divideing fractions nor multiply and i dont know most of my multiples
vladimir1956 [14]

Step-by-step explanation:

To multiply the fractions, like

\frac{1}{4}  \times  \frac{1}{9}

Multiply the top,

then multiply the bottom.

\frac{1}{4}  \times  \frac{1}{9}  =  \frac{1 \times 1}{4 \times 9}  =  \frac{1}{36}

Try to use a calculator if you aren't arithmetic heavy, but I suggest you to try to remember them because they are going to be helpful for courses like Algebra, Calculus, Statistics, etc.

To divide fractions, like

\frac{ \frac{1}{5} }{ \frac{1}{8} }

You take the top number,

\frac{1}{5}

Then you flip the bottom number,

\frac{8}{1}

Then multiply the two

\frac{1}{5}  \times  \frac{8}{1}  =  \frac{8}{5}

And that is your answer. Comment if you need more clarification
