Answer:

x=2

Step-by-step explanation:

The equation becomes 3x+9(2x)=42. Then you distribute the 9 into the 2x. Combine 3x and 18x for 21x=42. Divide 21 by both sides and you get x=2.

Find the Area of the shape<br> (Area of Composite Shapes)
Sloan [31]

Answer:

223.5 Km

Step-by-step explanation:

Area = Length x Width

Solving for Square Shape

8 · 6 = 48 km

Area = Length x Width

Solving for Rectangle Shape

Area = Length x Width ÷ 2

Solving for Triangle Shape

11 · 9 = 99 ÷ 2 = 49.5 Km

48 + 126 + 49.5 = 223.5 Km
