S2= 864/6
s = = 12 cm
p = 4/3 x 12 = 16 cm
t = 2/4 x 16 = 8 cm
l= 3/4x 16 = 12 cm
lp= 2 (pl+pt+lt)
= 2 (16 x 12 + 16 x 8 + 12 x8)
= 2 (192+128+96) = 832cm²
<span><span>If you would like to solve the equation </span>- 7 * x
- 3 * x + 2 = 8 * x - 8, you can calculate this using the following steps:<span>
- 7 * x - 3 * x
+ 2 = 8 * x - 8
- 7 * x -
3 * x - 8 * x = - 8 - 2
- 18 * x =
- 10 /(-18)
x = 10 / 18
x = 5/9
<span>The
correct result would be </span>5/9<span>.</span></span></span>

Step-by-step explanation:
Let the second train catch up after x hours
<span>Distance = speed X time </span>
<span>135x = 105 ( 2 + x) </span>
<span>135x = 210 + 105x </span>
<span>30x = 210 </span>
<span>x = 7 hours (after 2nd train has started ) </span>
<span>ANSWER 7 X 135 = 945 miles from the starting point </span>
<span>CHECK </span>
<span>7 X 135 = 945 miles </span>
<span>9 X 105 = 945 miles</span>
