Solve for w i’m just tired of answering these questions on ixl at this point so that’s why i’m here

-2.27 + 9.1w + 1.3w = -3.4w - 17.45

First, combine like terms

-2.27 + (9.1w + 1.3w) = -3.4w - 17.45

-2.27 + 10.4w = -3.4w - 17.45

Add 2.27 to both sides and 3.4w to both sides to isolate the w.

-2.27 (+2.27) + 10.4w (+3.4w) = -3.4w (+3.4w) - 17.45 (+2.27)

10.4w + 3.4w = -17.45 + 2.27

Simplify

13.8w = -15.18

Isolate the w. Divide 13.8 from both sides

13.8w/13.8 = -15.18/13.8

w = -15.18/13.8

w = -1.1

-1.1 should be your answer

hope this helps

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
