Answer:
C. 468mm²
Step-by-step explanation:
The formula for the surface area of rectangular prism is:
![A=2(wl+hl+hw)](https://tex.z-dn.net/?f=A%3D2%28wl%2Bhl%2Bhw%29)
Let's break down our variables.
L = 12mm
W = 6mm
H = 7mm + 2mm = 9mm
Now we substitute our values in the formula:
Step-by-step explanation:
-7(-3r+2)=3r-6
Distribute the - 7
21r-14=3r-6
Add 14
21r=3r+8
Subtract 3r
18r=8
Divide 18r by 8
2.25 should be the answer to r.
If both times are AM, or both are PM, AND they're both
on the same day, then 4:30 to 5:05 = 35 minutes.
(35 minutes) x (60 seconds / minute) = 2,100 seconds .
