Answer:
ok so first we know that 1/3 of a hour is 20 minutes since
60*1/3=20
so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15
20*15=300
300 minutes or 5 hours
Hope This Helps!!!

<span>The volume of a rectangular prism is
V = l · w · h
V= 252 cm3
h= 3 cm
l=5+W
W=x then l=5+x
V=(5+x)*x*3=252
3x</span><span>^2+15x=252 cm3
</span><span>
the equation that models the volume of the tray in terms of its width, x, in centimeters.</span>
3x^2 +15x=252 cm3<span>
</span>
for width=7.5 cm
3x^2
+15x=3*(7.5) ^2+15*7.5= 281.25 cm3
<span>281.25>252 </span><span> </span>
<span>it is not possible that the width is 7.5 cms</span>
Answer:
f(- 2) = 8
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 2
- 4(- 2)³ - 11(- 2)² +3(- 2) - 6
= 2(16) - 4(- 8) - 11(4) - 6 - 6
= 32 + 32 - 44 - 12
= 64 - 56
= 8
