Answer:
A) x^2-10x+25 B)X^3-15x^2+75x-125
Step-by-step explanation:
H^2=(x-5)(x-5)=x^2-10x+25
H^3=(x-5)(x-5)(x-5)=X^3-15x^2+75x-125
Answer: Find the greatest common factor, and put in parentheses outside of the expression
Step-by-step explanation:
The greatest common factor is the largest number that all terms are divisible by. Here is an example: 4x+8y+12 In this example the greatest common factor is 4. So, first we divide the expression by 4 and put it in parentheses, giving us (x+2y+3). However, (x+2y+3) does not equal 4x+8y+12. We need to put the 4 we divided by in front of the parentheses, giving us 4(x+2y+3), which does equal 4x+8y+12. Hope this helps
We will find the rate of Greg and Josh earning money that is
the amount of money they receive per unit time (hour)
Since the trip is in 3 weeks,
Number of hours Josh worked = 3 weeks * (5 hours/week) = 15
hours
Number of hours Greg worked = 3 weeks * (8 hours/week) = 24
hours
Josh’s rate = $480/15 hrs = $32/hr
Greg’s rate = $480/24 hrs = $20/hr
Therefore
Josh makes $12/hr more than Greg
