X^2 + 9 + 7 = 20
X^2 +16 = 20
X^2 = 20-16
X^2 = 4
Root 4 = 2
X=2
The correct expressions are
-8.8
11(-2)
-6.7
A = bh
b = 16
h = 3
A = 16*3
A = 48 square centimenters
Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A = 
and l = 
, thus
V = × ( cancel 21 and 3 by 3 and 2 and 8 by 2 )
= 
× 
= 7 × 4 = 28 units³
First, you would have to divide 7000 by 205. This gives you 34 & a remainder. The owner can't pack parts of a crate so yes he does because he only has 34 full crates to ship. Leaving him with 2 extra crates left.
