Answer:
-13
Step-by-step explanation:
2.5 * 2 = 5.
3.6 * 5 = 18.
5 - 18 = -13
Answer:
a). Distance from the surface of miner elevator=532 feet, Distance from the surface of equipment elevator=60 feet
b). The miner elevator is deeper since it is 472 feet deeper than the equipment elevator
Step-by-step explanation:
Equipment elevator speed=4 feet per second
Miner elevator=14 feet per second
Total time of miner elevator=(23+15)=38 seconds
Total time of equipment elevator=15 seconds
a). Distance from the surface of each elevator
Distance from the surface of miner elevator=Miner Speed×Miner Time
Distance=(14×38)=532 feet
Distance from the surface of equipment elevator=Equipment Speed×Equipment Time
Distance=(15×4)=60 feet
b). Which elevator is deeper
Distance from the surface of miner elevator=532 feet
Distance from the surface of equipment elevator= 60 feet
Difference=(532-60)=472 feet
The miner elevator is deeper since it is 472 feet deeper than the equipment elevator

Answer:
Step-by-step explanation:
The easiest way to solve this equation is to first find and highlight a common factor between two terms. In this case, x^2 can be factored to rewrite the equation as follows:
The (x+7) term can be crossed out on both sides and then for this equation to be true, there are two possibilities:
Either
or
Therefore, the solutions to this equation are -1, 1 or -7.
Answer:
Step-by-step explanation:
You need to use the distributive property to take out the common factor. But that doesn't tell you what the common factor is.
Look inside the brackets. You need to find something that is exactly the same on either side of the minus sign. In this case you have a huge cle about what it is.
2x^5 is it not? I'm assuming that's the correct way to read it.
So that's the answer to your question 2x^5.
The distributive property will tell you that 2x^5 can be taken out, and what is left is
2x^5 ( x^3 - 4)
