Answer:
D. 47 square units
Step-by-step explanation:
The area of the piece of red paper after the hole for the photograph has been cut is the difference between the area of large square and are of small square.
<u>Area of large square:</u>
The length of the side of large square is
Area of large square
<u>Area of small square:</u>
The length of the side of large square is
Area of small square
<u>Difference:</u>
4/52= 0.07692 so it would be C. 0.077
The slope of a line that is perpendicular to the line y = 8x + 5 will be -1/8.
<h3>What is the slope of perpendicular lines?</h3>
Suppose that first straight line has slope 's'
Let another straight line be perpendicular to this first line.
Let its slope be 'a'
Then due to them being perpendicular, they have their slopes' multiplication as -1
or
s x a = -1
s = -1/ a
Slope of line y = 8x + 5
s = 8
The slope of a line that is perpendicular to the line y = 8x + 5
8 x a = -1
a = -1/8
Thus, the slope is -1/8.
