Answer:
The area of the triangle should be: [(1 + 5 + 4) × 11]/2= 55 (ft²)
The area of the rectangle should be: 5 × 2 = 10 (ft²)
The area of the shaded region is: 55 - 10 = 45 (ft²)
It's the first choice. If you multiply the first equation by 3, your y term is a +12, and if you multiply the second equation by 4, your y term is a -12. When you add them the y terms cancel each other out.
<u>Answer</u>:
x = 
<u>Explanation</u>:
using sohcahtoa method:
middle line: 9 ÷ sin(45) = 9√2
x = sin(60) * 9√2 =
What those cm represent
you just have to apply the formula
if H=6cm
W=2
L=3
surface=2(wL +L*H+W*H)
=2(2*3+3*6+2*6)
=2*36=72 u^2
B is the answer to your problem
