It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.

Evaluate 10C4. Type a numerical answer in the space provided. Do not type spaces in your answer.

SOVA2 [1]

10C4 represent the Combinations of 10 objects taken 4 at a time.

The formula for nCr is:

$nCr= \frac{n!}{r!(n-r)!}$

In the given case, n=10 and r=4. Using these values we get:

$10C4= \frac{10!}{4!(10-4)!} \\ \\ 
= \frac{10!}{4!*6!} \\ \\ 
=210$

This means we can make 210 combinations of 10 objects taken 4 at a time.

9 - 10x = 2x + 1 - 8x

Furkat [3]

Answer:

$x=2$

Step-by-step explanation:

$9 - 10x = 2x + 1 - 8x$

$9-10x=-6x+1$

Subtract 9 from both sides:

$9-10x-9=-6x+1-9$

$-10x=-6x-8$

Add 6x to both sides:

$-10x+6x=-6x-8+6x$

$-4x=-8$

Divide both sides by -4:

$\frac{-4x}{-4}=\frac{-8}{-4}$

$x=2$

harkovskaia [24]

Answer:(x-3)(x-4)

Step-by-step explanation:Basically, the intercepts of the graph, 3 and 4, are when the graph is equal to zero, which is why is (x-3)(x-4) and not (x+3)(x+4).

Step-by-step explanation:

to solve this...we think that distance from ben to church is x...now a triangle is formed.

length of the hypotenuse is 13cm

${13}^{2} = {8}^{2} + {x}^{2}$
