Answer: 
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
You know that the dimensions of this rectangle are 5*10⁵meters and 4*10⁴ meters, then you need to multiply them to get the area:
Since 10⁵ and 10⁴ have equal base, you must add the exponents:
Scientific notation has the form:
Where "a" is any number between 1 and 10 but less than 10, and "n" is an integer.
Since 20 is greater than 10, you must move the decimal point to the left:
Rewriting the result, you get:
13 because 1 for every 2 would make it 4 times 2 which equals 8. add 8 to the 4 green toothpicks and you get 12.
Answer:
y= 12x -43
Step-by-step explanation:
y-5 = 12(x-4)
y-5= 12x-48
+5 +5
y= 12x- 43

Answer:
C. square
Step-by-step explanation:
<u>Congruent</u> means "the same" (having the same shape and size).
Any four-sided, 2-dimensional shape with straight sides is called a <u>quadrilateral</u>.
There are 6 special types of quadrilaterals:
<u>Rectangle</u>
- Opposite sides are parallel and equal in length
- All interior angles are 90°
<u>Square</u>
- All sides are equal in length
- All interior angles are 90°
<u>Rhombus</u>
- All sides are equal in length
- Opposite sides are parallel
- Opposite angles are equal
<u>Parallelogram</u>
- Opposite sides parallel and equal in length
- Opposite angles are equal
<u>Trapezoid</u>
- One pair of opposite parallel sides
<u>Isosceles Trapezoid</u>
- One pair of opposite parallel sides
- One pair of non-parallel sides equal in length
- Two pairs of equal base angles
<u>Kite</u>
- Two pairs of adjacent sides equal in length
- The angles included between the sides of differing lengths are equal
<u>Conclusion</u>
A four-sided shape that has four congruent angles and sides is a SQUARE.
