Answer:
6x - 5 = 67
6x = 72
x = 12
Step-by-step explanation:
setting the equation and variable x to the number
6 times the number and its difference to five is 67
plus five on both sides
divide both sides by 6
answer is 12

A = 81
Answer:
it would be 757.14
Step-by-step explanation:
Answer:
x = 6 cos t
y = 6 sin t
where t varies from 0 to 2pi
Step-by-step explanation:
Given that an ellipse is centred at the origin in xy plane.
So equation would be of the form

Major axis =2a= 12
so a=6
Minor diameter = 8
b = 8/2 = 4
a=6 and b =4
Also (6,0) should correspond to t=0
So best parametrization would be
x = 6 cos t
y = 6 sin t
where t varies from 0 to 2pi
