Answer:
(x+5) (x+5)
Step-by-step explanation:
1) You need to find two numbers that multiply to give you 25 but add up to 10.
2) This would be 5 and 5 as 5 times 5 gives you 25. Also, 5 plus 5 gives you 10.
3) to get x square you do x times x.
4) So: (x+5) (x+5)
Answer:
1) 75 copies were sold
2)expected wage=720
Step-by-step explanation:
in this equation, y represents wages and x represents number of copies sold
lets take the trendline, y=6x+120
since the amount earnt is $570, we can take this to be our y variable
570=6x+120
450=6x
x=75
1) 75 copies r sold
2) this time we substitue the 100 for x
y=6(100)+120
y=600+120
y=720
2) expected wage=720
