Answer: Steve's bedroom has the greater area.
Step-by-step explanation: The formula for area is Area = Length x Width.
So all you have to do to figure this out is multiply the Width of the rooms by the length.
So Steve's room is 12ft X 13ft = 156ft
Ricardo's room is 8ft X 14ft = 112ft
156ft > 112ft
Steve's room has a greater area.
Answer
8 minutes for 2 laps,
So 8x3=24,
So 2x3=6.
You can get around the track 6 times in 24 minutes.
Step-by-step explanation:
Plug in x = 7
<span>y= 330 - 25(x)
</span><span>y= 330 - 25(7)
</span><span>y= 330 - 175
y = 155</span>
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)
