Step-by-step explanation:
You should always use the least number of significant figures. The exception is exact numbers or constants.
For example, there are 60 minutes in an hour. Even though this number has one significant figure, it is an exact number. So 15 minutes converted to hours would be 0.25 hr.
Answer:
9(x+3) + 2(x+3) or 10(x+2) +(x+5)
Step-by-step explanation:
First you want to distribute the equation.
4(x+1) + 7(x+3) multiplied out is
4x + 4 + 7x + 21
Now we add like terms so it comes out to
11x + 25
Two expressions that can come out to equal 11x + 25 is. 9(x+3) + 2(x+3) or 10(x+2) +(x+5)
Answer:
The standard form of the equation of a circle is,
(x - h)² + (y - k)² = r²
where the center is at (h, k) and its radius is r. From the givens above, the equation of the circle is,
x² + y² = (12/2)²
or equal to x² + y² = 36.

Step-by-step explanation:
Given:
ABCD is dilated by a scale factor of 2 about point E.
To find:
The correct statement about the line segment E'E'.
Solution:
The center of dilation E lies on the line segment E'F' and the dilation factor is 2.
![E'F'=2EF](https://tex.z-dn.net/?f=E%27F%27%3D2EF)
Since the center of dilation E is one end point EF, therefore E and E' represents the same point.
It means, E'F' passes through the center of dilation.
Hence the correct option is D.
