Look for a pattern and complete the conjecture.
denis-greek [22]

Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is \frac{n}{2} (a+Tn)

The number of this series are 2, 4, 6, 8, 10, 12, .  .  .  .  , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + T_{30})

T_{30} = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

How to Factor 4p^2+4p-5
Anarel [89]

4p^2 + 4p - 5

As the expression cannot be factored in it's current form, we need to check if splitting the middle term is possible.

<em><u>List factors of -20.</u></em>

-5 * 4

5 * -4

-10 * 2

10 * -2

-20 * 1

20 * -1

<u>None of the factors added together result in positive 4.</u>

Because splitting the middle term is not possible, and we cannot simplify this expression any further:

This expression cannot be fully factored.

Which system of equation should you use to solve this problem
Alex17521 [72]

Last option is the correct answer.

Step-by-step explanation:

Given that

Let x stand for the solution a and y stand for the solution B

So,

According to statement that

30 gallons have to be made

x+y=30

Solution A contains 29 percent bromine => 0.29x

Solution B contains 53 percent  =>0.53y

And the mixture of 30 gallons contains 45% bromine

0.29x+0.53y=30*0.45\\0.29x+0.53y=13.5

Following equations will be used for solving the problem

x+y = 30\\0.29x+0.53y=13.5

Hence,

Last option is the correct answer.
