x=8
Step-by-step explanation:
move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8
Answer:
quadrilateral DEFG is reflected to form a quadrilateral D'E'F'G'
Step-by-step explanation:
Vertices DEFG are in a clockwise orientation. Those in D'E'F'G' are in a counterclockwise orientation. The only way vertex order is reversed is through reflection. Translation, rotation, or dilation will not do that.
quadrilateral DEFG is reflected to form quadrilateral D'E'F'G'
Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°
Equal - you can remember by ‘equil’ in equilateral sounding a lot like equal
The equation of a circle is:
where center is (h,k) and radius is r. Therefore, in this question, you need to check if the (h,k) values are the same. Let's view each option and judge accordingly:
A. (0,-4) and (-4,0) : Nope
B (-3,3) and (3,-3) : Nope
C. (7,2) and (-7,-2) : Nope
D. (2,5) and (2,5): Yes, the centers are equal.
Therefore, your answer is option D.
