For this case, the first thing we must do is define variables.
We have then:
x: number of cubic yards of mulch that first truck can transport
y: number of cubic yards of mulch that second truck can transport
Now we write the expression.
The first truck makes 12 trips to a job site:

The second makes 14 trips:

The difference between the first truck and the second truck is:
Answer:
An expression that represents the difference in the total number of cubic yards that the first truck delivers compared to the second is:
X2+16 is the prime <span>polynomial.
x2+16 is the only </span><span>polynomial that couldn't be factored out anymore
x2-36 --> (x-6)(x+6)
x2-7x+12 --> (x-3)(x-4)
x2-x-20 --> (x+5)(x-4)</span>
Answer:
4
When you divide powers you take them away but when you times them you add them
Answer:
Step-by-step explanation:
Answer: 32
Step-by-step explanation:
Given: The energy needed for 1 hour of running for an adult 
Therefore. the energy needed for seven hours of running=
Since, he energy released by metabolism of 1 average candy bar 
Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.=
Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.
