Answer:
When we know all 3 sides, we use Heron's Formula
area = sqrt [s *(s-a) * (s-b) * (s-c)]
where "s" is the semi-perimeter which in this case equals
s = (6 + 8 + 12) / 2 = 13
area = sqrt [13 * 5 * 7 * 1]
area = sqrt 455
area = 21.3307290077
area = 21.33 square feet (rounded)

Answer:8 x 365=2920
Step-by-step explanation:
First, you add 5 + 3 which equals 8. Then there is 365 days in a year so you would multiply 8 times 365 which equals 2920.
Pretty sure this is right, hope it helps.
Answer: Non-Linear Function line
Step-by-step explanation:
The reason is if it was a linear one then it would be a straight line and since this is not a straight line then it is a Non-Linear Function because you can't just look at it and see what the increase and decrease was for a certain time period.
Answer: three dimensional figure and plane.
Step-by-step explanation:
A cross section is the intersection between a (three dimensional figure) and also a (plane).
When an object is being cut straight, the shape that we get is referred to as the cross section. We should note that several parallel cross sections will be firmed when we cut a particular object into slices.
