To solve this, you use the rule where AK x KC = DK x KB. In this case, 14(3+3X) = 12(4X+1). Then you solve like it's basic algebra. Your answer is then x=5. Or in this case answer choice D.
F(x) = -4sin(2x + π) - 5
<u>Amplitude</u>
A = -π
<u>Period</u>

Answer:
Step-by-step explanation:
4^2+x^2 = 15^2
x^2 = 15^2 - 4^2 = 225-16 = 209
x=sqrt(209)
x = 14.46
Answer:
Option D - x = 3 3/5
Step-by-step explanation:
Lets make the left side into an improper fraction :
2 2/5 = 12/5
Now let's make both fraction into equivalent ones but with the same denominator :
2/3 = 10/15
12/5 = 36/15
Now we substitute the equivalent values back into the equation :
10/15 × x = 36/15
Now we multiply both sides by 15 to remove the denominators:
10 × x = 36
Now we divide both sides by 10 and simplify :
x = 36/10
x = 18/5
x = 3 3/5
So our answer will be Option D
