5x + 10y + 5z. Distribute the .5 to the number in the parentheses. It basically just cuts the numbers in half.
Answer:
c
Step-by-step explanation:
Answer:

No maximum
Step-by-step explanation:
Given

Solving (a): The minimum
The minimum is when the absolute parameter gives 0
i.e.

Divide both sides by 0.9

Open bracket

Remove absolute sign

Collect like terms

Then the y value is:

Recall that: 
So, we have:


Hence, the minimum is at: 
Since the minimum is at
, then the graph will open upwards.
Hence. the function has no maximum; i.e.

The formula for the area of a triangle is Area=.5(b)(h)
So fill in what you know:
120=.5b*15
Then solve for b.
120=7.5b
b=16
Answer:
4/10=2/5 therefore the answer to 2/5
