Answer:
Width = 5.5ft, Length = 8ft.
Step-by-step explanation:
Area of Rectangle = Length x Width
Let w be the Width of the rectangle.
From the information given from the question,
Length = 2w - 3 (3ft less than twice the width)
Area of Rectangle = = 44
Now we can solve for w to find the dimensions.
(Quadratic Equations)
We can use the Quadratic formula to find w.
Since a = 2, b = -3 and c = -44,
We reject negative values here.
Therefore, the width of the Rectangle = 5.5ft
While the length of the rectangle = 2(5.5) - 3 = 11 - 3 = 8ft
Step-by-step explanation:
3x-6x+5(3x-2)+8x
Opening bracket
= -3x + 15x - 10 + 8x
= 12x + 8x - 10
= 20x - 10
= 10(2x - 1)
Answer:
time left for question C = 12 1/2
Step-by-step explanation:
Total time required for the three quiz= 30 minutes
time spent on question A= 10 9/10 minutes
Time spent on question b= 6 3/5 minutes
Time spent on Question c= Total time required for the three quiz -( time spent on question A+Time spent on question b)
30 - ( 10 9/10 + 6 3/5)
30 -16 (9+ 6/10)
30- 16 15/10( 15/10 = 1 5/10)
30 - 16 + 1 5/10
30 - 17 5/10
From 30, we remove 1 whole number to subtract the fraction from the other number so we have
29 - 17 ( 1 -5/10)
=12 5/10 = 12 1/2
What. This makes no sense. I am screaming in pain an confusion. Why have you chosen to do this. You need to give me detailed questions if you want people to answer. I am sorry that I cannot come up with a solution.
