Answer:
1)-0.65 2) 28.8 3) 747.6
Step-by-step explanation:
- divide the numerator (-13) and the denominator (20)
- 32 x 90= 2880, divide 2880 by 100 equals to 28.8
3. multiply 12 by 62.3
I hope this helps!
The domain of a(x) is all of R. The domain of b is the range where

. We can calculate the composition boa by changing in the expression for b, every x with a(x). Hence, boa(x)=

=

. Again for a function with a root to be defined, we need that the expression under the square root has to be positive. Hence, 3x-3

0.Thus, the set where this holds is

. This is also the domain of the function boa(x).

Step-by-step explanation:
1) Given problem,

LCM(5,4) = 20,



2) Given problem,

LCM(6, 4) = 12,



3) ∵ Pizza ate by Manny = 
Pizza ate by Frank = 
∴ Total pizza eaten = 
LCM(4, 8) = 8,

Thus, total pizza eaten = 
I think it would be obtuse, triangle, and a cute
