Step-by-step explanation:
Expanded notation may be defined as the way of expressing a number by exhibiting its value of each of the digit.
In an expanded notation, the number is always represented as a summation of each of the digit times its place value, while in the expanded form, an addition is used between the place value numbers.
A number containing zero can be written in the expanded form as for example,
509,300
Since digit 5 is 100,000th place, 9 is in 1,000th place and the digit 3 is 100th place, the number can be written as --
5 x 100,000 + 9 x 1,000 + 3 x 100
Answer:
1017.36 square miles
Step-by-step explanation:
Since the diameter of a circle is twice the radius, the radius of this circle is 36/2=18. Since the area of a circle is 
, the area of this circle is:

Answer: 1. No 2. yes 3. yes 4. no
Step-by-step explanation:
If you locate the points on the graph, 1 and 4 are not in the shaded and 2 and 3 are, which means they are not solutions.
Answer:
12
Step-by-step explanation:
hope it helps you on what ur doing
Solution:
1. Move all terms to one side
<span>25{x}^{2}+40x+16-28=0</span>
2. Simplify <span>25{x}^{2}+40x+16-28 to <span>25<span>x<span><span>2</span><span></span></span></span>+40x</span></span><span><span>−12</span></span>
<span>25{x}^{2}+40x-12=0</span>
3. Apply the Quadratic Formula<span>x=\frac{-40+20\sqrt{7}}{50},\frac{-40-20\sqrt{7}}{50}
</span>
4. Simplify solutions
<span>x=-\frac{2(2-\sqrt{7})}{5},-\frac{2(2+\sqrt{7})}{5}</span>
Done!
