What is the factor of y = 4x2 +2x -30

Korolek [52]3 years ago

<span>What are the factors of y=4x^2 + 2x - 30?

First, divide 2 out of this expression.  y = 2(2x^2 + x - 30)

One way to factor this would be to find the roots using the quadratic formula:

Since a=2, b=1 and c= -15, 
        -1 plus or minus sqrt(1^2-4(2)(-15)
x = -------------------------------------------------
                           4
         -1 plus or minus sqrt(121)         -1 plus or minus 11
    = -------------------------------------- = ----------------------------
                        4                                            4

One such solution is -12/4, or -3.  The corresponding factor is (x+3), and the other is 5/2, leading to the factor (2x-5).

Therefore, </span><span>4x^2 + 2x - 30 = y = 2(2x-5)(x+3).</span>

Answer:

  • 6912xy^8

Step-by-step explanation:

The 9th term is the next-to-last term, where the left term of the binomial is raised to the first power, the right term of the binomial is raised to the 8th power (9-1=8), and the multiplier is 9C8 = 9!/(8!·1!) = 9. This product is ...

  9·(3x)^1·(-2y)^8 = 6912xy^8

Round 24.99 to the nearest tenth
klasskru [66]
A tenth of 24.99 would be the first 9 after the point. In order to round it to the nearest tenth, we must look at the number after it. If that number is 5 or above, we must make the tenth one higher. In this case, the number after the tenth is above 5, so we change the tenth to a 1! Now the number becomes 25.00

Two angles are complementary. The measure of one angle is 6º more than five times the measure of the other angle. Find the
Salsk061 [2.6K]

Complementary means that the two angles sum to 90 degrees.

So based on the problem, let:

1st angle=5x+6

2nd angle=x

Now create an equation.

x+5x+6=90

6x=84

x=14

5x+6=76

answer: 14 degrees and 76 degrees

Reporting Stockholders' Equity
DaniilM [7]

The total stockholders equity based on the information given will be $8285000.

<h3>How to compute the equity?</h3>

The stockholders equity will be calculated thus:

Common stock $4480000

Excess over par = $1152000

Paid in capital = $5632000

Sale of treasury = $224,000

Total paid in capital = $5856000

Retained earnings = $2,554,000

Total = $8,410,000

Less treasury stock = 125,000

Total stockholders equity = $8,410,000 - $125000

= $8285000

Therefore, the total stockholders equity based on the information given will be $8285000.
