In this problem there might be a number that you need to add before the "( x 3)" then your answer will be 20 = 32 - 12 = 20

It should be 4? Both sides have to be equal. The answer to the 4 x (8-3) is 20 because 8-3 = 5 and 4 x 5 = 20. On the other side 4x8 = 32. The missing number in the next set of paranthesis needs to equal the number that will subtract from 32 to make the answer 20... the parathensis should be 4x3 because it = 12.

4 x (8-3) = (4x8) - (4x3)
4 x 5 = 32 - 12
20 = 20

What is a necessary step for constructing perpendicular lines through a point off the line?

mixas84 [53]

Draw arcs on either side of a given point on the line

To construct a line perpendicular to another line through a point on the line:

Measure a length from that point to one edge of the line

Draw two intersecting arcs on either sides of the line

Draw a straight line from the intersecting point of the arcs to the point on the existing line.

The new line drawn is a perpendicular line.

The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"

Option C is the correct choice
