Answer:
24
Step-by-step explanation:
The pyramid is made up of 4 large triangles. So if you use formula for the triangle
where b = 6 and h = 2 after plug you will get 6.
Now times them by 4 because you have 4 triangles so you will end up with 48.
Let's say x = 16. In the equation 4 + x(3/x) then you use 16 instead of x. So it would look like 4 + 16(16/3). 4 plus 16 times 16 divided by 3.
The answer to your problem is 1.8
Answer:7
Step-by-step explanation:none
Answer:
see below
Step-by-step explanation:
This is an arithmetic sequence. The explicit formula for an arithmetic sequence is aₙ = a₁ + (n - 1)d where a₁ is the first term and d is the common difference. In this case a₁ = 9 and d = 6 so we have:
aₙ = 9 + (n - 1) * 6
aₙ = 9 + 6n - 6
aₙ 6n + 3
