Answer:7m^5 - 3m^3 + 9
Step-by-step explanation: You’d have to remove the brackets, but remember that the second has to have everything multiplied by -1, because there’s a minus sign in front of the second bracket. Then you’d group like terms, then add or subtract. Here’s the step by step
6m^5 + 3 - m^3 - 4m + m^5 - 2m^3 + 4m + 6
2. 6m^5 + m^5 - 2m^3 - m^3 + 4m - 4m + 6 + 3
Subtract or add what’s needed, which would be figures with the same variable and coefficient.
3. 7m^5 - 3m^3 + 9
After this, there’s nothing you can add, since the remaining figures don’t have the same variable.
Hope it’s clear and this wasn’t that long
Domain : 4 ,1 ,0
Range : 2 ,1 ,0 ,-1 ,-2
This one is pretty easy.
x+ 4 = 7
Subtract 4 from both sides so you can isolate the x (Get the x alone)
x = 7 -4
x = 3
That's your answer. 3.
The probability of the union of two events is the sum of their probability, minus the probability of their interserction:
If we plug the known values into this formula, we have
From which we can deduce
So, the probability of 
is a bit less than 
, we have to take away all events that belong to B as well:
Answer:
I believe the second h=25+70t -16t
Step-by-step explanation:
because the initial height is 25 thats where you have to start and every second your adding 70 that way it's + 70t... but I don't get where the 16 comes in so I may be wrong
