Answer: 140

Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D

What is the product? (3x-6) (2x^2 -7x+1)
STALIN [3.7K]

<u>Answer-</u>

\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6

<u>Solution-</u>

Given the two polynomials are 3x-6, 2x^2 -7x+1

So their product will be,

=\left(3x-6\right)\left(2x^2-7x+1\right)

Distributing the Parentheses,

=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1

Applying minus-plus rules,

=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1

Simplifying further,

=6x^3-33x^2+45x-6

Alessandro wrote the quadratic equation –6 = x2 + 4x – 1 in standard form. What is the value of c in his new equation?
Black_prince [1.1K]

Answer:

5

Step-by-step explanation:

To write it in standard form, we set the equation equal to 0.  To do this, we add 6 to each side:

-6+6 = x² + 4x - 1 + 6

0 = x² + 4x + 5

The related function is

y = x² + 4x + 5

The value of c in this function is 5.

Mrs. Habib has 46.25 feet of border for a bulletin board for her classroom. the board is 37.5 feet tall and 8.3 feet wide. how m
Luba_88 [7]

Answer:

Mrs. Habib will have 22.25 feet of border left after she puts border around the board.

Step-by-step explanation:

You must find the perimeter of the board and subtract it from the amount of border she has to find how much she will have left after she uses it. The formula for perimeter is P=2(l+w), where l= the length of the board, and w= the width of the board. You will add those together and multiply them by 2 because there are 4 sides to a rectangle. That means this equation will look like:

P=2(8.25+3.75)

Now you can just solve for the perimeter.

P=2(12)

P=24

The perimeter is 24 feet. That means it will take 24 feet of border to cover her board. In order to find out how much she'll have left over, just subtract 24 from the total amount of border she has.

46.25-24=22.25

Therefore Mrs. Habib will have 22.25 feet of border left over after she covers the bulletin board.
