Answer:
<h2>9</h2>
Step-by-step explanation:
(-)(-) = (+)
(-)(+) = (-)
(+)(-) = (-)
(+)(+) = (+)
-(-21) = (-)(-21) = (+)21 = 21
-12 - (-21) = -12 + 21 <em>use commutative property: a + b = b + a</em>
= 21 + (-12) = 21 - 12 = 9
(2)
we know that
when two lines do not intersect , they can be parallel lines or skew lines
so,
Lines that do not intersect are called <u>parallel or skew lines</u>
(4)
we know that
A circle is the set of all points in a plane that are equidistant from a given point
so,
The set of points in a plane that are equidistant from a given point form a <u>circle</u>
(8)
Moving a figure around a fixed point in the plane is called making <u>a image of the figure</u>
(3)
A <u>translation</u> of the plane is a transformation which shifts all the points in a plane figure, without altering the shape of the figure
(6)
All the points on a line that are between two given points form a line <u>segment</u>

Answer:1490
Step-by-step explanation:so while solving this question, you want to make sure the decimals are on top of each other. 8+8 is 16 so you write 6 and carry 1. 4+9 is 13 +1 =14, write 4 carry one across the decimals. 5+4 is 9 plus 1 equals 10 write zero carry 1. 7+1 is 8 plus 1 is 9 so you write that down and since 1 and 4 have no numbers under them, you write it down too giving you 1490.46
