First, move 9x^2 to the right:
7y^2 = 42 - 9x^2
Then, divide 7 on both sides:
y^2 = 6 - 9/7 * x^2
Answer:
360
Step-by-step explanation:
The exterior angles always add up to 360 in a polygon because it's the sum of all the vertexes which would make a circle.
Answer:
The number is 35.
35 divided by 7 is 5, and 5 plus 7 is 12.
