Answer:
8n + 46
Step-by-step explanation:
Combine like terms. First, simplify the signs. two negatives directly next to each other equals one positive:
- (-5n) = + 5n
30 + 5n + 16 + 3n = (30 + 16) + (5n + 3n)
(30 + 16) = 46
(5n + 3n) = 8n
8n + 46 is your answer.
<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

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>
