Think about it this way: 0.4 is read as what?
It's read as "four tenths".
This means that it can also be said as "four out of ten".
So, 0.4 into a fraction is "4/10".
Now, this fraction can be reduced, so what is the greatest common factor of 4 and 10?
Factors of 4: 1,2,4
Factors of 10: 1,2,5,10
So the greatest common factor is 2.
So, if you divide both 4 and 10 by the greatest common factor to get (4/2) = 2 and (10/2) = 5.
So, the reduced fraction would end up being 2/5.
When you divide 2 by 5, you get 0.4, if you want to check.
f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
Replace f(x) and g(x) with their given values:
h(x) = -2x + 4x -8
Combine like terms:
h(x) = 2x -8

Answer:
25.5
Step-by-step explanation:
A=(hbb)/2=(3·3)/2=4.5 A = Triangle
B= 5x6= 30 B = Square
B-A= Answer!
30-4.5 = 25.5
