1/3
Step-by-step explanation:
sin=p/h
p/h= 3/9
3/9=1/3
X ^ 2 - 9
= x ^ 2 - 3 ^ 2
It turns into 3 ^ 2
Because 3 ^ 2 = 9
The final answer is
= ( x + 3 )( x - 3 )
remember the formula :
a^2 - b^2 =(a+b)(a-b)

Answer:
1/12 of a mile.
Step-by-step explanation:
1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.
2. Multiply each fraction (numerator and denominator) to convert them.
1/3(4/4) = 4/12
1/4(3/3) = 3/12
3. Subtract.
4/12-3/12 = 1/12
