Step-by-step explanation:
Length = x-3
width = x+8
Area of the rectangle = 60 inch²
(x-3)(x+8)=60
x²+8x-3x-24=60
x²+5x-24=60
x²+5x-84=0
x²+12x-7x-84=0
x(x+12) - 7(x+ 12) =0
(x+12)(x-7)= 0
x= -12 or, x= 7
Measure of sides of rectangle can never be negative.
Answers:
Therefore,
x=7
Dimensions
length =7-3
=4 inches
width = 7+8
=15 inches
Answer:
43 tickets were sold on one day
Step-by-step explanation:
250 tickets for the school dance were sold and on Monday, 35 tickets were sold.
This means that after Monday, the number of tickets sold were:
250 - 35 = 215 tickets
This means that 215 tickets were sold for the next five days.
If an equal number of tickets were sold on those 5 days, then, the number of tickets sold on each day is:
215 / 5 = 43 tickets
Therefore, 43 tickets were sold on each of the five days (43 tickets were sold on one day).
