A= Area
l= length
w= width
l= w-3cm
A= l*w
A= 53cm²
53= l*w
(plug in value of length)
53= (w-3)(w)
0=w²-3w+53
Use the quadratic formula:
(in the pictures attached)
w= about 9cml=9-3=

2x-3y=6
3y=2x-6
y=2/3x-2
Slope = 2/3
Therefore B
Answer:
30 i think
Step-by-step explanation:
Converting from one units to another set of units, a conversion factor is needed. For this problem, the conversion factor would be 1 mile = 1610 m. We convert the value of <span>speed</span> of light from meters/second to miles/hour as follows:
3 x 10^8 m/s (1 mile / 1610 m) ( 60 s / 1 min ) ( 60 min / 1 hr ) = 6.71 x 10^8 miles / hr
Answer:
Option 1) is correct
Step-by-step explanation:
Given: The graph shows the distance in miles, m, hiked from a camp in h hours.
To find: hourly interval that had the greatest rate of change
Solution:
Rate of change between two points refers to the vertical change divided by the horizontal change.
For hour 0 to hour 1:
rate of change = 
For hour 2 to hour 3:
rate of change = 
For hour 1 to hour 2:
rate of change = 
For hour 3 to hour 4:
rate of change = 
So, rate of change is greatest in interval: hour 0 to hour 1
