4 could be considered a common factor
0.8w + 3.6 =
4(0.2w + 0.9)
or you could call 0.4 the common factor
=0.4(2w+9)
= (2/5)(2w+9), if you want to eliminate decimals. 0.4=4/10=2/5
Answer:
Approximately 11 feet.
Step-by-step explanation:
Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:
=
+
- 2abCos C
⇒
=
+
- 2(8 x 12) Cos
= 64 + 144 - 192 x 0.42262
= 208 - 81.143
= 126.857
x = 
= 11.2631
x ≅ 11
The length of the third side of the triangle is approximately 11 feet.
