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:
or
Answer:
x-2>-3
x>-3+2
x<-1
Step-by-step explanation:
qhen you get this type of question remove the bracket from there and write x-2>-3 after that you will move -2 to -3 so when you move it the symbol negative will change to positive the you will subtract positive 2 from the -3 and your answer will be x<-1
Answer:
3x + 4 = 12
Step-by-step explanation:
plus = +
equal = =
but if you were looking for the answer to the equation
3x + 4 = 12
3x = 12 - 4 (the symbol changes bc i switched it to the other side)
3x = 8
x = 8/3
