Answer:
s = 1.81
Step-by-step explanation:
4.4(1.81)+6.2=8.8(1.81)-1.8
plug in and multiply if you'd like to clarify :)
<span>96-2r=6r-112
Add 2r to both sides
96=8r-112
Add 112 to both sides
208=8r
Divide 8 on both sides
Final Answer: 26=r</span>
Scalene I think. Sorry it's been forever but and equilateral triangles sides are all, well, equal and an Isosceles triangle has only 2 sides the same length.
Area=legnth times width
legnth=6
area=6x+18
subsitute
6x+18=6 times width
undistribute 6 from each term on left side
6(x+3)=6 times width
divide both sides by 6
x+3=width
