Answer:
372 m²
Step-by-step explanation:
A vertical line down the center of the figure will divide it into two congruent trapezoids, each with bases 13 and 18, and height 12.
The area of one of them is ...
A = 1/2(b1 +b2)h
So, the area of the two of them together is ...
A = (2)(1/2)(b1 +b2)h = (b1 +b2)h
A = (13 m + 18 m)(12 m) = 372 m²
- 3a + 6
subtract and add like items together like
- 4a + a = -3a
b-b= 0
and
9-3 = 6
so the answer is
-3a +6
x = -(4/3)
I think y= -1/3x
sorry if wrong
