Answer:
Surface area of the box is 
Step-by-step explanation:
The box is in the shape of a cuboid:
Surface area of the cuboid = 2(L*W+W*H+H*L)
Length(L)=20.1 m
Width(W)=6.8 m
Height(H)=7.4 m
Surface area:

The surface area of the box is 
Answer:
[1] = 6
x = -3/2 is the root
Step-by-step explanation:
A perfect square trinomial is of the form ...
(a + b)² = a² +2ab +b²
You have ...
- a²=16w² ⇒ a = 4w
- b² = 36 ⇒ b = 6
- 2ab = 2(4w)(6) = 48w
Then the factorization is ...
16w² +48w +36 = (4w +6)²
This will be zero when x = -6/4 = -3/2.
If M is the midpoint of segment RS, then
M = (R + S)/2
2M = R + S . . . . . multiply by 2
S = 2M - R = 2(8, -2) -(10, 5) = (6, -9) . . . . put in the given values
