X=13 1/3
So first you have to add 16 +4 = 20. Then, simplify 3/2 to 1.5. Finally divide 20 by 1.5 = 13.333333333, or 13 1/3
I believe A and B are the ones. As for explaining? hmm. I would honestly say that any number to the right of a number is a tenth of the place above it. But then again, it's optional to explain ;P
Answer:
139.5
Step-by-step explanation:
A= (a + b) /2 *h
A = ( 13 + 18) /2 *9
A = 31 / 2 * 9
A = 15.5 * 9
A = 139.5
The area of the composite figure is
A.) 32 cm^2
Hope this helps! :)
