pounds.
Weight of the One World Trade Center building= 88,200,000 pounds.
=
The addition of the two:

Comparing with the form: 
a=8.182 and b=8
Answer:
x= -1/2
Step-by-step explanation:
Answer: d = 0.5
Step-by-step explanation:
2d - 9 = 5d - 3 (3d + 2)
2d - 9 = 5d - 9d - 6
2d - 9 = -4d - 6
+ 4d +4d
6d - 9 = -6
+9 +9
6d = 3
/6 /6
d = 0.5
Shape 1: TRIANGLE
Formula: A = 1/2 x bh
1/2 x (10)(5) = 25
AREA: 25 square yards
Shape 2: RECTANGLE
Formula: A = lw
(12)(10) = 120
AREA: 120 square yards
Sum (ADD)
25 yd^2 + 120 yd^2 = 145 yd^2
The area of the composite figure is 145 yd^2
