Let Sister's age now = s
So Larry is now s + 8
In THREE Years Sister = s + 3
Larry = {s + 8} + 3
But We are told that he will be TWICE as old as Sister is NOW!!!
So s + 11 = {2s}
Solve s = 11
So Sister is ELEVEN Years old and Larry is NINETEEN Years old.
Answer:
A
Step-by-step explanation:

x+2=0
x+2-2=0-2
x=-2.....(x+2) was squared...exponent of 2...multiplicity of 2
x-4=0
x-4+4=0+4
x=4....(x-4) has no visible exponent which means it is essentially to the power of 1...multiplicity of 1
x+1=0
x+1-1=0-1
x=-1....(x+1) was cubed...exponent was 3...multiplicity of 3
No, the correct identity is

. It is obtained by dividing the both sides of the Pythagorean Trigonometric Identity by cos²(x):
