Divide (x^2 - 5x - 6) by (x -6) with long division<br> show steps please!!
Katyanochek1 [597]

Answer:

  see below. Quotient is (x +1).

Step-by-step explanation:

The general process is identical to numerical long division. You find a quotient term, multiply that by the divisor and subtract the result from the dividend to make a new dividend.

For polynomial long division, the quotient term is the ratio of the highest-degree terms of the dividend and divisor, so is easy to calculate without the guesswork involved in numerical long division.

For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches
pashok25 [27]

Answer:

Option 1st is correct

3 \cdot (\frac{1}{2} \cdot  10 \cdot 5)=x

Step-by-step explanation:

Area of the triangle is given by:

A = \frac{1}{2}bh

where,

A is the area of the triangle

b is the base and

h is the height of the triangle.

As per the statement:

For a project, you need to make three triangles out of cardboard.

Each triangle has a height of 5 inches and a base of 10 inches

⇒b = 10 inches and h = 5 inches

\text{Area of each triangle} = \frac{1}{2} \cdot  10 \cdot 5

Since,  you need to make three triangles out of cardboard

⇒\text{Area of 3 triangle}(x) =3 \cdot (\frac{1}{2} \cdot  10 \cdot 5)

Therefore, an equation can you use to solve for the total amount of cardboard you will need is,

3 \cdot (\frac{1}{2} \cdot  10 \cdot 5)=x

Bernard solved the equation 5 x + (negative 4) = 6 x + 4 using algebra tiles. Which explains why Bernard added 5 negative x-tile
LenaWriter [7]

Answer:

To find why he would do this, we need to understand what all the possible first steps are in this equation.

You could add 4 to both sides.

You could subtract 4 from both sides.

You could subtract 5x from both sides.

You could subtract 6x from both sides.

Any of these work. In Bernard's case, he added 5 negative x tiles, meaning he subtracted. C and D already make no sense, but allow me to further explain. By him subtracting 5x from both sides, the equation turns into:

-4 = x + 4

By this point, he can just subtract 4 from both sides to find the value of x. But the question asks for why he did the first step. Therefore, it would
