Answer:
<h2>9</h2>
Step-by-step explanation:
(-)(-) = (+)
(-)(+) = (-)
(+)(-) = (-)
(+)(+) = (+)
-(-21) = (-)(-21) = (+)21 = 21
-12 - (-21) = -12 + 21 <em>use commutative property: a + b = b + a</em>
= 21 + (-12) = 21 - 12 = 9
15 + 6(x + 1)
First, expand to get rid of parentheses.
Second, simplify. Keep your 6x and add 15 + 6.
Answer:
6x + 21
5 kilometers in meters are 5000, 1 kilometer is 100 meters
