Solve the following quadratic equation. (x + 4)2 = 361
A.
x = -23 and x = -15
B.
x = 23 and x = 15
C.
x = 23 and x = -15
D.
x = -23 and x = 15

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

x = 12

y = 1

for the points!

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)
