Answer: x=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15x+9=3(2x−6)

15x+9=(3)(2x)+(3)(−6)(Distribute)

15x+9=6x+−18

15x+9=6x−18

Step 2: Subtract 6x from both sides.

15x+9−6x=6x−18−6x

9x+9=−18

Step 3: Subtract 9 from both sides.

9x+9−9=−18−9

9x=−27

Step 4: Divide both sides by 9.

9x/9 = -27/9

x=−3

Answer:

x= -3

Step-by-step explanation:

First let's work on the right side and use distributive property

15x+9= 3(2x-6)

15x+9= 6x-18

    -9         -9

15x= 6x-27

-6x  -6x

9x= -27

9x/9= -27/9

x= -3

Hope this helps!

Is EFGH below a rectangle
poizon [28]

Answer:

  D. No, because EFGH is a parallelogram but it’s diagonals are not congruent

Step-by-step explanation:

The differences between the end points of the diagonals are ...

  F -H = (1, 1) -(2, -5) = (1 -2, 1 -(-5)) = (-1, 6)

  G -E = (4, -2) -(-1, -2) = (4 -(-1), -2 -(-2)) = (5, 0)

The length of FH is more than 6, the length of GE is exactly 5. The diagonals are different length, so the figure cannot be a rectangle.

__

The midpoints of the diagonals will be in the same place if the sum of their end points is the same. (Dividing each sum by 2 gives the midpoint of that segment.)

  F+H = (1, 1) +(2, -5) = (3, -4)

  G+E = (4, -2) +(-1, -2) = (3, -4)

The diagonals bisect each other (have the same midpoint), so the figure is a parallelogram.

EFGH is a parallelogram, but not a rectangle: its diagonals are not congruent.
