maw [93]

Answer: x = -14/5

Step-by-step explanation: We shall begin by expanding the brackets for both sides of the equation

-2/3 (x + 2) = 1/6 (x + 6)

(-2x/3) -4/3 = (x/6) + 1

By collecting like terms we now have

(-2x/3) - (x/6) = 1 + 4/3

(-4x - x)/6 = 7/3

-5x/6 = 7/3

By cross multiplication we now have

-5x (3) = 7 (6)

-15x = 42

x = -(42/15) {simplify further by dividing the RHS by 3}

x = -14/5

Therefore x equals, minus fourteen over five (-14/5)

Checkpoint Quiz 1<br> 1. Write a formula for finding the area of a parallelogram.<br> le
azamat

Answer:

The formula for area of a parallelogram is either A=bh or A=\dfrac{d_1d_2}{2}.

Step-by-step explanation:

If base and vertical height of a parallelogram are given, then the area of the parallelogram is:

A=bh

Where, <em>b</em> is base and <em>h</em> is the vertical height of the parallelogram.

If measures of both diagonals are given, then the area of the parallelogram is:

A=\dfrac{d_1d_2}{2}

Where, d_1,d_2 are the two diagonals of the parallelogram.
