The correct answer is x^2-6x+8
Answer: 1/2
Step-by-step explanation:
1) Put the equation into y=kx form
- add 4x to both sides
- divide by 8 on both sides to get y=1/2x
2) k is the constant of proportionality
The answer to that is 0.80 which is f because you convert the answer like you would do normal equations
Answer:
728 m^2
Step-by-step explanation:
There are 5 faces of the square pyramid.
You have to calculate area of each face and add them to find surface area.
Bottom face is a square, so
area = 14^2 = 196 m^2
All the other faces are triangle with same area, so
4 × triangle area
4 × ((1/2)×14×19)
4 × 133
532 m^2
Now add those areas,
(196 + 532) m^2
728 m^2
