4/7 is not equal to 8/12. It is not equal because if you 4x2= 8 is equal but if you do 7x?= 12 it would be a decimal and you need equal numbers to make it a equivalent fraction. If it was 4/7= 8/14 that would be equivalent.
Hope I helped! : -)
25x² - 36 = 0
25x² - 30x + 30x - 36 = 0
5x(5x) - 5x(6) + 6(5x) - 6(6) = 0
5x(5x - 6) + 6(5x - 6) = 0
(5x + 6)(5x - 6) = 0
5x + 6 = 0 or 5x - 6 = 0
- 6 - 6 + 6 + 6
5x = -6 5x = 6
5 5 5 5
x = -1.2 x = 1.2
X = 13, Y = 10
I'm a bit tired right now, so I'm not going to explain my work, but hopefully this still helps.
Good luck with your schoolwork/homework!

Answer:
Step-by-step explanation:
In this sequence a=7
d=11.5-7=4.5
So 46th term = a+45d
=7+45(4.5)
=7+202.5
=209.5
