4(x – 5) +2x = -14
So x=?

x=1

Step-by-step explanation:

Step 1:Simplify both sides of the equation

4(x-5)+2x=-14

(4)(x)+(4)(-5)+2x=-14

4x+-120+2x=-14

4x+2x+-20-14

6x+-20=-14

6x-20=-14

Step 2: Add 20 to both sides

6x-20+20=-14+20

6x=6

Step 3: Divide both sides by 6

6x/6=6/6

x=1

yes because they have the same amount of green and blur marbles.

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
