Answer:
4 ft.
Step-by-step explanation:
We can consider the orignial square's sides to be x, so area of the original figure: 
The new rectangle's sides will be x and x+8, so the area of the new figure will be x^2+8x.
We know that the new area is 3 times the old one. So our equation will be:
x^2+8x=3x^2
our answer will be x=4.
Therfore, the length of the side of the old flower bed is 4 ft.
Answer:
y = 2x + 3
Step-by-step explanation:
y = 2x - 8 passes through ( 1,5 )
y = 2x + 3 is parallel to y = 2x - 8 because it has the same m( 2x)
and it also passes through ( 1, 5 )

Hope this helps
Independent variable on x-axis (value you can choose)
dependent variable on y-axis (corresponding value for the value you have chosen)
You can the hours and the distance traveled is a function of those hours.
also, I'd go in increments of 5. More accurate than increments of 15. The answer is D! <span><span>

Answer:
<h2>
6 1/2 lbs</h2>
Step-by-step explanation:
Given the weight of granite to be 74 26/36 lbs,
Weight of quartz is 81 9/40 lbs.
To know how much more quartz weight than the granite, we will take the difference between the weight of quartz and granite as shown.
Weight of quartz - Weight of granite
= 81 9/40 - 74 26/36
= 3,249/40 - 2690/36
= (29, 241 - 26,900)/360
= 2,341/360
= 6 181/360
≈ 6 1/2 lbs
quartz weighs approximately 6 1/2 lbs much more than granite
