× = -t/p
Step-by-step explanation:
By collecting like terms you will have a new equation
h - t - h = px
Then both h will cut out leaving
-t = px
dividing both side by p will give you
x = -t/p
The correct answer is the 3rd option
Answer:
or
Step-by-step explanation:
Let:
Given
Solving (a): The polynomial for the volume in terms of height
Volume (V) is calculated using:
Expand
Open brackets
Rewrite as:
Solving (b): The dimensions when Volume = 180
Substitute 180 for V in:
Rewrite as:
Factorize:
Express as difference of two squares
This gives:
Since the height can not be negative, then H = 5 or H = 6
Recall that:
When H = 5
When H = 6
Hence, the dimensions of the box are:

I am so so sorry, i know what it feels like to lose a friend. the advice i was given was to be nice to them even if they are mean to you and try to get your mind off it. i can suggest listening to music and watching minecraft twitch streamers like tommyinnit dreamwastaken and georgenotfound seriously, they help anxiety and boredom. try to stay calm when in court and if you look it up on the internet, there is a military method to sleep that makes me settle down to sleep. then you can take deep breaths and maybe listen to white noise or music. so so sorry this is happening to you :((
