The definition is pretty simple:
So, we only have to sum the expressions:
Answer:
Perimeter= 49
area= 360
Step-by-step explanation:
perimeter means you need to add 40+9 and area means you must multiple the numbers.
No it is not a function, because a function cannot have more than one output per input. When x=-3, there are two solutions shown: (-3,2) and (-3,3), therefore it cannot be a function.
Answer:
2/4 or 1/2
Step-by-step explanation:
2/4 or 1/2 is the greater fraction.
Find a common multiple in between the denominators.
10 and 3 and 5 -> the least common multiple is 30.
Change all the denominators to 30 by multiplying the top and bottom by the same number.
9/10=27/30
1/3=10/30
1/5=6/30
Subtract!
27/39-10/30-6/30=11/30
The answer is 11/30
Hope this helps!
