Answer:

8y^3 + 6y^2- 29y + 15

Step-by-step explanation:

(4y-3)(2y^2+3y-5)\\4y(2y^2 + 3y - 5) - 3(2y^2+3y-5)\\8y^3+12y^2-20y-3(2y^2+3y-5)\\8y^3+12y^2-20y-6y^2-9y+15\\8y^3+6y^2-29y-9y+15\\= 8y^3+6y^2-29y+15

In the diagram shown, AE 1/3AC and ED ll CB. Explain why df must be one-fourth length of CD
Blizzard [7]

The value of the length DF is 1/4 of that of CD because of the Angle Bisector Theorem for triangles.

<h3>What is the Angle Bisector Theorem?</h3>

The Angel Bisector Theorem states that if a ray bisects an angle of a triangle, it dissects the side of the triangle that is opposite to the dissected angle into parts that are proportionate to the adjacent sides.

Note that the angle that has been dissected here is ∠CBD. Thus,

\frac{DF}{CF} = \frac{BD}{BC}

a game cost $30 and a stoe bought it and sold it for $50. what is the percent makeup???????????????? need help ASAP!
PIT_PIT [208]

Answer:

67%

Step-by-step explanation:

Cost plus markup = selling price.

Here, the cost was $30 and the selling price was $50.  Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.

We now compare this $20 to the original cost ($30):

$20

------- * 100^ = 67%

$30

The markup, as a percentage, was 67%.

How do you do 44.70 divided by 15 long division
-BARSIC- [3]

Since the divisor is 2 digits, start by looking at the first 2 digits of the dividend. Those are 44, so you're dividing 44 by 15 at the first step. The quotient digit is the largest integer that gives a value less than or equal to the dividend (44) when multiplied by the divisor (15). For the first step, that digit is 2.

To find the new divisor, subtract the product of the divisor and the quotient digit (2·15=30) and bring down the next digit of the original dividend. Now, you have a dividend of 147 and a divisor of 15. Repeat the process as above.

The decimal point location in the answer can be found a number of ways. The simpliest is to put it above the decimal point in the dividend. (When the divisor is not an integer, multiply or divide both divisor and dividend by the same power of 10 until it is.)
