Answer:

Step-by-step explanation:
We are given the two functions:

And we want to find:

This is equivalent to:

Substitute:

Distribute:

Rearrange:

Hence:

Volume of a pyramid = 
Given base is = 140 m
Given height is = 96 m
Volume = 
Hence, volume of pyramid is 4480 m³
The length equals: 28 then height equals 13.2 because you do perim divide by length which gives you height, then u check and do 13.2 times 28 and get 369.6 then you just round the 6.
Yes, that is the famous first Pythagorean triplet: 3²+4²=5²
or
For three lengths to be able to form a triangle, it suffices that every one of those lengths is shorter than the sum and longer than the difference of the other two.
It is enough to check just one side.
So,
3 + 4 > 5
4 - 3 < 5
Your triangle is constructible.
