Answer:

z=13

Step-by-step explanation:

Ok we are to solve for z from the given equation

2z=26

It's like making z the subject of formula

We will be able to think fast on how to make z the subject of formula from the equation

To make z the subject of formula we will have to divide both sides by 2

z=13

Therefore the value of z is 13

To solve this kind of question you must be to think on ways to eliminate the number behind the required number

Hope you understand

Answer: z = 13

Step-by-step explanation: Since <em>z</em> is multiplied by 2, divide both sides of the equation by 2 to get <em>z</em> by itself and show all your work! That leaves you with z = 13 which is the solution to this equation.

Put both sides of the equation over 2 and cancel out the 2's on the left side just like I have done in the image provided.

Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay of for you down the line.

Answer:

  Part A: 2 ft²

  Part B: draw a diagonal (AC, for example); 1 ft²

Step-by-step explanation:

<u>Part A</u>:

The area of a parallelogram is given by the formula ...

  A = bh

where 'b' is the length of the base, and 'h' is the perpendicular distance between the bases.

Using the numbers shown on the diagram, the area is ...

  A = (3 ft)(2/3 ft) = 3·2/3 ft²

  A = 2 ft² . . . . . area of the parallelogram

__

<u>Part B</u>:

Typically, a polygon is partitioned into triangles by drawing diagonals from one of the vertices. It does not matter which one. (In a quadrilateral, only one diagonal can be drawn from any given vertex.) Here, the "base" of each triangle is the same as the base of the parallelogram: 3 feet. The "height" of each triangle is the same as the height of the parallelogram: 2/3 ft.

The area of a triangle is given by the formula ...

  A = 1/2bh

  A = 1/2(3 ft)(2/3 ft) = (1/2)(3)(2/3) ft²

  A = 1 ft² . . . . . . . . area of each triangle

_____

<em>Additional comment</em>

It should be no surprise that the area of each of the two congruent triangles is 1/2 the area of the parallelogram.
