Answer:

7x^2-4x+3y^2 ( the ^ means the exponent EX: 5^2 is 5 squared. )

Step-by-step explanation:

Remove the parenthesis (a) = a

12x^2-11y^2-13x- (5x^2-14y^2-9x)

-(5x^2 - 14y^2 - 9x)

Distribute parenthesis

-(5x^2) - (14y^2) - (-9x)

Apply minus - plus rules

-5x^2 + 14y^2 + 9x

= 12x^2 - 11y^2 - 13x - 5x^2 + 14y^2 + 9x

Simplify

12x^2-11y^2-13x-5x^2+14y^2+9x

Group like terms

12x^2-5x^2-13x+9x-11y^2+14y^2

Add similar elements

7x^2-13x+9x-11y^2+14y^2

Add similar elements ( - 13x + 9x = -4x )

7x^2-4x-11y^2+14y^2

Add similar elements 11y^2 + 14y^2 = 3y^2

7x^2-4x+3y^2

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.
