You need to isolate 'y' so subtract 1 from both sides.
y < 5
Draw out a small graph and count the units of each side, then add all four numbers to get the perimeter.
Find the area of the rectangle with the circles. Then find the area of each of the circles and add them together and minus that from the rectangle’s area.
A of rectangle = 30x10 = 300
A of circle = pi x r squared = pi x 25
A of shaded region = 300 - 75 pi = 68.3805cm square
Answer:
aₙ = 3n - 5
5th term = a₅ = 3.5 - 5 = 15 - 5 = 10
