X - 14 = 52
move - 14 for + 14
x = 52 + 14
x = 66
So this is going to be alot of writing to show my thinking but ill bold the answer.

next ill mark all the ones that equal 4 or 8 when added together, with an x
1,1
1,2
x1,3

that is 6 (that equal 4 or 8) out of 25
so your ratio would be 6:19
Answer:
Step-by-step explanation:
I think you have the question incomplete, and that this is the complete question
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
To do this, we can start my mirroring the equation.
x² + y² = (x + y)² - 2xy,
This helps us break down the power from 4 to 2, so that we have
(sin²a)² + (cos²a)² = (sin²a + cos²a) ² - 2(sin²a) (cos²a)
Recall from identity that
Sin²Φ + cos²Φ = 1, so therefore
(sin²a)² + (cos²a)² = 1² - 2(sin²a) (cos²a)
On expanding the power and the brackets, we find that we have the equation proved.
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
Answer:
should be 64:3
