What is the simplified form of x minus 4 over x squared minus x minus 12 ⋅ x minus 4 over x squared minus 8x plus 16 ?

Step-by-step explanation:

The expression we are given is

We factor the denominator of each expression.

To factor

x²-x-12, we find factors of -12 that sum to -1.

-4(3) = -12 and -4+3 = -1; this gives us

Cancelling the common factors in the numerator and denominator, we have

To factor

x²-8x+16, we find factors of 16 that sum to -8;

-4(-4) = 16 and -4+-4 = -8.  This gives us

Cancelling the common factors in the numerator and denominator, we have

This gives us

answer: idk

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
