3cos (x) / 5 + 4sin (x)/ 5
this is simplified
8 / x = 12 - 3(8)
8 / x = 12 -24
8 / x = -12
x = -0.66666666667
Check your work
8 /(-0.66666666667) = 12- 3(8)
-12 = 12 - 3(8)
-12 = -12
x = -0.66666666667 Exactaly (Ten 6's One 7)
Hope this helps :)
The pattern starts at 2/14 and increases by 1/14 each node, so the next fraction is 6/14 which simplifies into 3/7
Answer:

Step-by-step explanation:
(a²-b²) / (a+b) = 12
a² - b² = 12(a+b)
(a-b)² + 2ab - 2b² = 12a + 12b
(a-b)² = 12a + 12b - 2ab + 2b²
a - b =

that would be A. 312 x 10^6
we can find this by counting the zeros
312,000,000
that's 6 zeros, so that means it's 312 x 10^6
