To find the answer for that question you have to find the area of rectangle first, so you say 60*80 which equals to
4800 cm squared and then find the area of the box and not its volume so you say: 2(16*10)=2*160=
320 cm squared 4(16*27)=4*432=
1728 cm squared add 320+1728=
2048 cm squared Finally, to find the area of the left poster board you have to subtract the area of the rectangle which is 4800 cm squared by the area of the box which is 2048 cm squared so 4800-2048=
2752 cm squared

</span><span>A </span>reflection<span> over a line k (notation </span><span>rk</span><span>) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line. Remember that a reflection is a flip. Under a reflection, the figure does not change size.
</span>
The line of reflection is the perpendicular bisector of the segment joining every point and its image.</span>
<span>A line reflection creates a figure that is congruent to the original figure and is called an isometry (a transformation that preserves length). Since naming (lettering) the figure in a reflection requires changing the order of the letters (such as from clockwise to counterclockwise), a reflection is more specifically called a non-direct or <span>opposite isometry.

Answer:
-2
Step-by-step explanation:
2x + y = 7 is the equation of the given straight line.
Let us arrange the above equation in slope-intercept form as
2x + y = 7
⇒ y = - 2x + 7 ...... (1)
The slope-intercept form of a straight line is given as y = mx + c, where, m is the slope and c is the y-axis intercept of the straight line.
Therefore, - 2 is the slope of the given straight line (1).
Hence, the slope of the line that is parallel to (1), is -2. (Answer)
{Slope of two parallel straight lines are of same value}
