Answer:
a = 27
b = 38
c = 19
Step-by-step explanation:
a + b + c = 84
b = 2c
a = 8+c
8+c +2c+c = 84
4c + 8 = 84
4c = 76
c = 19
b = 2(19) = 38
a = 8 + 19 = 27
A number outside of the square root symbol is actually multiplied by the square root of the number under the symbol. 25 and 9 are considered perfect squares because a number multiplied by itself goes evenly into each without any remainders.
=3√25 - √9
take the square root of 25 and 9
=3(5) - 3
multiply 3*5
=15 - 3
=12
ANSWER: 12 (first choice)
