- 12 + x ≥ 3 (x - 6)
- or, 12 + x ≥ 3x - 18
- or, 12 + 18 ≥ 3x - x
- or, 30 ≥ 2x
- or, 30/2 ≥ x
- or, 15 ≥ x
- or, x ≤ 15

Answer:
Step-by-step explanation:
sin x=a+b
cos x=a-b
sin²x+cos²x=(a+b)²+(a-b)²=2a²+2b²
or 2a²+2b²=1
a²+b²=1/2 which is constant for all values of x
(ii)

100%-47%(discount) so she is paying 53% of original price now,
100%. $13.99
53%. $X
X=13.99•53/100
X=741.47/100
X=7.4147
She was charged $7.41
the answers that you've provided are, in fact, correct.
Answer: Our required ratio would be 4:1.
Step-by-step explanation:
Since we have given that
Let the distance at which the stone lands from building B be 'x'.
Let the distance at which the stone lands from building A be '4x'.
So, we need to find the ratio of building A's height to building B's height.
As we know that
Ratio of distance at which stone lands from building B : Ratio of distance at which stone from building A = Ratio of height of building A to Ratio of height of building B.
So, Ratio of height of building A to Ratio of height of building B is given by

Hence, our required ratio would be 4:1.
