Step-by-step explanation:
l = 3x - 5
w = 2x + 9
perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =
= 6x - 10 + 4x + 18 = 10x + 8
area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =
= 6x² + 17x - 45
The diameter splits the circle into 2 equal halves by going through the midpoint of the circle. The two halves are called semicircles.
Step-by-step explanation:
m-(-3)>17
m +3>17
m >17-3
m>14
