Answer: x^3 + x^2 - 17x + 12
Step-by-step explanation:
(x+4)(x^2-5x+3)
x^3 - 5x^2 + <u>3x</u> + 4x^2 <u>- 20x</u> + 12
underlined and bolded can be combined
That leaves you with x^3 + x^2 - 17x + 12
From 1-60, 4 and 6 a few common multiples. Find those multiples, which are
12, 24, 36, 48, 60.
So in 60 seconds, they blink together 5 times.
You mean the difference between a number X and 12 is 20. What is the X?
X-12=20
X=20+12
X=32
