Answer:
y = 9x - 40
Step-by-step explanation:
Using the point-slope equation of a straight line is the fastest approach here, since we already have the slope and a point:
y - k = m(x - h) becomes y - 5 = -9(x + 5)
Solving for y, this becomes y = 9x + 5 - 45, or y = 9x - 40
Answer:
Octagon
Step-by-step explanation:
Formula for a polygon is :
- a = apothem (distance from center to the midpoint of a side
- P = perimeter (sum length of the sides)
Since a regular octagon has 8 sides, and a regular hexagon has 6, the octagon will have the greater area due to greater perimeter.
if the other side is 15 inches and the area is 90 square inches:
90/15 = 6
height = 6 inches (A)
