Given that:
Brian's age = 27
Age of Chris is 17 more than one - fourth of Brian's age.
To find:
Age of Chris = ?
Solution:
Let age of Chris = 
One - fourth of Brian's age = 
17 more than One - fourth of Brian's age = + 17
Therefore, we can write the equation as per question statement:
Therefore, Chris is 23.75 years old if Brian is 27.
Since all the sides of a square are the same, all we need to do is take the square root of the area.
√143 = 11.958260...
How to round:
5 and above, round up
4 and below, round down
11.958260... -> 12
Therefore, the side lengths of the square is aproximately 12 feet.
Best of Luck!

Answer:
20
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x
Substitute x = 2 into f(x) + g(x)
(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20
