Find the value of x (6x + 1) (9x-23)

Step-by-step explanation:

Alright we are going to be using F.O.I.L

(6x + 1) (9x-23)  Apply F.O.I.L

6x*9x+6x(-23)+1*9x+1*(-23)  Remove parenthesis

6x*9x+6*23x+1*9x+1*23

Step 2

6x*9x+6*23x+1*9x+1*23

So you simplify

54x^2-129x-23

Your Simplified answer is 54x^2-129x-23

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
