3
Step-by-step explanation:
An equation for that would be.
x => 67
Answer:
6.5500
Step-by-step explanation:
The <u>answer would be 6</u>. The number line which shows you the number 6 or any solution for 6 would be your answer.
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
