Answer: 665,640 minutes
Step-by-step explanation:
Dimensional analysis: dividing out common units like dividing out common factors
<em>For ex: </em>3/5* 5/7= 3/7
cross out the fives and turn them into 1
For dimensional analysis you just cross out the units.
days-->hours-->minutes
462.25d/1* 24h/1d* 60m/1h= 665,640 minutes
Cross out the d's and h's.
You are left with minutes on the top and no units on bottom.
Just multiply across to get the answer 665,640 minutes
Subtract 2d from both side
3d+8=2d-17
-2d -2d
1d+8=-17
-8=-8
1d=-25(divide 1 from both side
D=-25
( 2(x^2) + 6x + 6 ) * ( 3x - 2 )
= 6(x^3) + 14(x^2) + 6x - 12
so the answer is D
