The formula for the area of a square of side s is A = s^2.

Then s^2 = A, and s = +√A.

Answer:

$3x+2y+4=27$

Step-by-step explanation:

Let

x ----> represents the number of 3-point field goals

y ----> represents the number of 2-point field goals

we know that

The number of 3-point field goals multiplied by 3 plus the number of 2-point field goals multiplied by 2 plus the number of free throws (4) multiplied by 1, must be equal to 27 points

The equation that represent this situation is

$3x+2y+4=27$
