Answer with explanation:
Pyramid and Plane both are three dimensional shapes.
Pyramid is a three dimensional shape having base any polygon and other faces as triangles.
The base of pyramid is horizontal.
1. If lower base is a Square,or rectangle or any other parallelogram
And, then , plane cuts the pyramid vertically
It will be also, a three dimensional shape ,resembling a triangular cross section in three dimension.
Triangle is appropriate choice.
Original height of tree = (x+5) m
In triangle ABC x square = 5 square + 12 square
X square = 25+144
X square = 169
X = 13
Thus the original height of the tree was 13+15 = 18m
Answer:
assuming x2 is x^2:
f(x) = (x+4)^2 - 3
Step-by-step explanation:
1. move c to f(x) side
2. make sure a=1
3. (b/2)^2
4. add the solution of 3 on both sides
5. factor the right side using the shortcut
6. add c back to the other side
