Answer:
6
Step-by-step explanation:
6 is in the middle with 2 numbers on each side so it is the medium
A. 135 B. 45 C. 45 I believe or A and B are switched... so ( A. 45, B. 135)
A
substitute x = 3h into f(x)
f(3h) = 2(3h)² + 3(3h) - 4 = (2 × 9h²) + 9h - 4 = 18h² + 9h - 4
Answer:
a ≈ 8.9
Step-by-step explanation:
Set up the equation as so:
8a^2 + 2 = 634
First, subtract two from both sides:
8a^2 = 632
Then, divide by 8 to further isolate the variable.
a^2 = 79
To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
If you are saying:
(3/12) - (8/12)
Then since their denominators are the same we can subtract the numerators to get our answers.
3 - 8 = -5
Following the rule of adding and subtracting fractions, the denominators will not change unless they are different.
So: (3/12) - (8/12) = -5/12
