3.2 gallons
You see what you do is you divide 120 by 37.5 and you will get the number of gallons
Answer:
Step-by-step explanation:
To answer this question we should analyze both functions :
- the intercepts with the x-axis are the numbers when a function f(x)=0
here we must solve both equations :
- x²=0
- x²+2=0
the first one is obvious x=0 the scond is more interesting :
x²+2=0⇔x²=-2 wich is impossible since x²≥0 unless we use complex numbers .
So we notice thatf has one intercept.
we added 2 to f to get g but no real intercepts
The object is to get everything except for "h" on one side of the equation.
The equation says that everything on the right side is being multiplied by 1/2.
What do we have to multiply times 1/2 to get 1? The answer is 2.
So multiply both sides by 2 to get rid of the fraction.
2A = (a+b)h
Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.
(a+b)/(a+b) is 1
So you are left with: 2A/(a+b) = h
Done!
