to see that
. Substituting into the original equation gives
, proving the desired statement.
Answer:
x = -13.5
Step-by-step explanation:
4 + 2/3x = -5
1. subtract 4 on both sides.
2/3x = -9
2. divide 2/3 on both sides.
x = -13.5

Answer:
c = -6
Step-by-step explanation:
Answer:
It is called a rectangular prism
It has 8 vertices
<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
</span>
<span>Sum of Interior Angles = (7 -2) * 180
</span>
<span>Sum of Interior Angles = 5 * 180
</span>
<span>Sum of Interior Angles = 900 degrees
