Find the approximate side length of a square game board with an area of 149 in. squared.

→ Formula:

• substitute for the area:

• take square roots on either sides:

answer: i guess 5 units?

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
