Subtract 3 3/4 from 10 1/2. Note that the LCD is 4, so 10 1/2 = 10 2/4.

What is 10 2/4
- 3 3/4
-------------------------
?

Since 2/4 is smaller than 3/4, you must borrow 1 from that 10.

Now your problem looks like 9 6/4
-3 3/4
----------
6 3/4 (answer)

The remnant of the board is 6 3/4 feet long.

Simplify the difference quotient f ( x + h ) â f ( x ) h for the function f ( x ) = 6 x â x 2

ladessa [460]

Answer:

final answer is 6

Step-by-step explanation:

Given $f(x)=6x-2$

To find the difference quotient use formula

$\frac{f(x+h)-f(x)}{h}$

$f(x)=6x-2$

$f(x+h)=6(x+h)-2=6x+6h-2$

Now plug it in the formula

$\frac{f(x+h)-f(x)}{h}$

$\frac{6x+6h-2-(6x-2)}{h}$

$\frac{6x+6h-2-6x+2)}{h}$

$\frac{6h}{h}$

Factorise 12u-uv please help lol

max2010maxim [7]

Answer:

u(12-v)

Step-by-step explanation:

12u and -uv both have a factor of <em>u </em>in common, so we can pull it out to give us the factored expression u(12-v).

<em>Note on factoring:</em>

<em>Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.</em>
