Answer:

The expression which is equivalent to (6c² + 3c)/(-4c + 2) ÷ (2c + 1)/(4c - 2) is -3c.

Step-by-step explanation:

The given fraction is:

(6c² + 3c)/(-4c + 2) ÷ (2c + 1)/(4c - 2)

Simplify the equation:

3c(2c+1) / -2(2c - 1) ÷ (2c +1)/2(2c-1)

Change the division sign into a multiplication sign

3c(2c+1) / -2(2c - 1) × 2(2c-1)/(2c+1)

Cancelling 2(2c-1) :

3c(2c+1)/ -1 × 1/(2c+1)

Cancelling 2c+1 :

3c/-1 × 1/1

Simplifying:

-3c

Hench the given fraction is equals to -3c.

Two of the vertices of a rectangle are (1, −6) and (−8, −6). If the rectangle has a perimeter of 26 units, what are the coordina
pantera1 [17]

Answer:(x_1,y_1)=(1,-2)

(x_2,y_2)=(-8,-2)

Step-by-step explanation:

Given

Co ordinates of vertices(1,-6) and (-8,-6)

When two points is given then Length of two points is given by

L=\sqrt{\left ( x_2-x_1\right )^2+\left ( y_2-y_1\right )^2}

L=\sqrt{\left ( 1-\left ( -8\right )\right )^2+\left ( -6+6\right )^2}

L=\sqrt{9^2}=9 units

Perimeter of rectangle is =26 units

Let the other side be x

thus

2\left ( x+9\right )=26

x+9=13

x=4 units

therefore to get the other two co ordinates

such that the length of that side is 4 units is

(x_1,y_1)=(1,-2)

(x_2,y_2)=(-8,-2)

Horizontal distance will remain same only vertical distance will change in given co ordinates to obtain the remaining two co ordinates

To verify the above two  distance between two points must be 13 units

Which number line best shows how to solve -2-(-4)
pantera1 [17]
Alright. -2-(-4) = -2 + 4 because a negative and a negative equals to a positive[(-2-(-4)]. It would look like: Put a dot on -2, then move your dot 4 units to the right, which is +2.
