Answer:
The answer is D
Step-by-step explanation:
when you are dividing two numbers with an exponent you want to subtract the exponents.
7-4 =3
5/12
Since 12 inches is one foot, the number has to be a fraction number. The answer is 5/12 feet.
a = 10, c = 15, b = 5√5
a = 8, c = 18, b = 2√65
a = 12, c = 14, b = 2√13
a = 4, c = 20, b = 8√6
a = 12, b = 14, c = 2√85
a = 4, b = 20, c = 4√26
a = 10, b = 15, c = 5√13
a = 8, b = 18, c = 2√97
