D) Number of bags to sell
Answer: (-9,4)
Step-by-step explanation: First, we set the equation equal to zero by subtracting 36 from both sides to get x² + 5x - 36 = 0.
Next, we factor the left side of the equation
as the product of two binomials.
Since the factors of -36 that add to +5 are +9 and -4,
we have (x + 9)(x - 4) = 0.
This means that either x + 9 = 0 or x - 4 = 0.
Solving each equation from here,
we have x = -9 or x = +4.
So your solution set is (-9,4).
Let m be my age in years.If s is my son's age in years, then my son is 52s weeks old. If g is mygrandson's age in years, then my grandson is 365g days old. Thus,
365g = 52s.
Since my grandsonis 12g months old,
12g = m.
Since my grandson,my son and I together are 120 years,
g + s + m = 120.
The above system of3 equations in 3 unknowns (g, s and m) can be solved as follows.
m / 12 + 365 m /(52 x 12) + m = 120 or
52 m + 365 m + 624m = 624 x 120 or
m = 624 x 120 /1041 = 72.
So, I am 72 yearsold.
The problem is hard...i don't know if you understood this..Hope i helped!
