Answer:
47.5
Step-by-step explanation:
He is 68.
Even though he is half your age, that doesn't mean that he will be half your age all your life. That just means he will be X years younger.
If you need an example:
Your brother was two when you are four. So when you become 6, your brother will be come 4. The fact that he is half your age doesn't really matter once you start growing up, because he will never be half you age again.
Answer:
The answer is the Greatest Common Factor (GFC).
Step-by-step explanation:
Answer:−2n+6,−2n+6
Step-by-step explanation:
5n+6−7n,5n+6−7n
((5n−7n)+6),((5n−7n)+6)
−2n+6,5n−7n+6
−2n+6,((5n−7n)+6)
−2n+6,−2n+6
What do you mean by "solve this?" Until you set f(x) = to some constant number, you don't have an equation and thus can't expect to find solutions.
Why don't we take <span>3x^2-18x+27 and set it = to 0, and only then try to solve this equation?
</span><span>3x^2-18x+27 = 0. Dividing both sides by 3, we get x^2 - 6x + 9= 0, which can be factored as
(x-3)^2 = 0. Taking the sqrt of both sides, we get x-3 = 0. Actually, there are 2 roots: 3 and 3. Again, this statement is true only if we set </span><span>3x^2-18x+27 = to 0.</span>
