Answer: -231 ft
<u>Step-by-step explanation:</u>
The submarine started at sea level = 0
It submerged 140 ft = -140 ft
It traveled 40 miles horizontally so it is still at -140 ft
It dove down an additional 120 ft = -260 ft <em>(-140 + -120)</em>
It traveled 25 miles horizontally so it is still at -260 ft
It rose 29 ft = -231 ft <em>(-260 + 29)</em>
Note: submerged and dove are negative values and rose is positive
0 - 140 - 120 + 29 = -231

Answer:
6 + 3
+ 2
+ 
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Given
(3 + )(2 + )
Each term in the second factor is multiplied by each term in the first factor, that is
3(2 + ) + (2 + ) ← distribute both parenthesis
= 6 + 3 + 2 +
Answer:
-15e+14f-30
Step-by-step explanation:
First using distributive property to expand the first term:
-21e+14f-28+6e-2
Combining like terms:
-15e+14f-30
