Step by Step Instructions:

really all you have to do is subtract the exponents. 12^7-12^3=12^4, if you want to expand the numbers you can do it that way too. 12^7=35831808, 12^3=1728, 35831808/1728=20736 (which is the same as 12^4)

Part B: how can you decompose this parallelogram into two triangles. If this parallelogram was decomposed into two triangles what would be the area of each triangle?

Answers

Answer: Area of the 2 triangles is 6

Step-by-step explanation: The area of the two triangles that inside to parallelogram is 6. I found that out by putting 6 at the top and 2 on the side so its base and height then I multiplied 6 and 2 and got 12 so I divided 12 by 2 and got 6 so Area of triangle is A = 6

The area of the parallelogram ABCD is 2 square feet.

What is Quadrilateral?

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The area of quadrilateral is base times height

Area of parallelogram=2/3×3

=2 square feet.

Parallelogram can be decomposed in 2 triangle by joining either AC or BD

Area of triangle = (1/2) x base× height

Hence area of each triangle = (1/2) Area of the parallelogram

= (1/2) × 2

= 1 sq feet

Hence, the area of the parallelogram ABCD is 2 square feet.

Angle 3 is 65 degrees. solve for x if angle 5 is equal to 5x.

Answers

Answer:

X=23

Step-by-step explanation:

If angle 3 measures 65 degrees the so does angle 2, 7 and 6. By the definition of parallel lines. Then by the definition of supplementary lines angle 5+ angle 7=180 degrees, so 5x+65=180 => 5x=115 => [tex]\frac{5x}{5}[/tex]=[tex]\frac{115}{5}[/tex] => x=23.

Answer:

No

Step-by-step explanation:

Just substitute the letters. x = 7 and y = 0. Then just solve and see if it works out.

0 = 3 · 7 - (-7)

0 = 21 - (-7)

0 = 28

That is a false answer so no. (7,0) is not a solution.

Answers

Answer:

x = 10; x = 0

Step-by-step explanation:

x < 29 means x is less than 29. Any number less then 29 is a solution.

For example, pick x = 10. Since 10 < 29, x = 10 is a solution. How do we know x = 10 is a solution?

We start with x < 29.

Now replace x with 10.

10 < 29

Since 10 < 29 is a true statement, then x = 10 is a solution.

Now pick another number less than 29. For example, oick 0.

x = 0 is a solution.

Proof:

x < 29

Replace x with 0:

0 < 29

Since 0 < 29 is a true statement, then x = 0 is a solution.

You can give more solutions just by picking any numbers that are less than 29, such as 1, 2, 3, 15, 28, 23, -5, -18, etc.

Answer: x = 10; x = 0

Put in any two numbers less than 29 like -29, 23, 17, 6, or any number less than 29
