Answer:
(x + 1)(x + 4)
Step-by-step explanation:
We want to factor x² + 5x +4 into two binomial factors. Note that 1*4 = 4 and that 1 + 4 = 5, so:
y = x² + 5x +4 = (x + 1)(x + 4)
Answer:
416
Step-by-step explanation:
Volume = length * width * height
8*5*10.4 = 416
Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make 
of the total work. If the same analysis is applied Niko, in 1 minute, will make 
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make 
of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:
