Answer:
11
Step-by-step explanation:
Here, x - 2y = 14
x = 14 + 2y
Now, substitute this value into first equation,
4x + 6y = 0
4(14 + 2y) + 6y = 0
56 + 8y + 6y = 0
14y = -56
y = -56/14
y = -4
Substitute it into second equation,
x = 14 + 2(-4)
x = 14 - 8
x = 6
In short, Your Answer would be: (6, -4)
Hope this helps!
bear in mind that it goes with the "degree" of the polynomial.
Radius is half of diameter so the diameter would be so 1.5 and 6. And circumference is 2(pi)(radius). So that's around 9.4 for the first question and 38 for the second
