Need to construct a square, mikayla uses her straightedge to draw line ab . she will use the method of constructing a square which will make line ab a diagonal of the square. what should mikayla do next? open the compass to the length of ab¯¯¯¯¯ and draw a circle centered at point a. without changing the compass opening, draw a circle centered at point b. open the compass to the length of ab¯¯¯¯¯ and draw a circle centered at point a. change to compass opening to half the length of ab¯¯¯¯¯ and draw a circle centered at point b. put the compass point on a and the pencil point on the segment, closer to point a than to point b, and draw a circle centered at point a. without changing the compass opening, draw a circle centered at point b. put the compass point on a and the pencil point on the segment, closer to point b than to point a, and draw a circle centered at point a. without changing the compass opening, draw a circle centered at point b.

The answer is the fourth option. Put the compass point on A and the pencil point on the segment, closer to point B than to point A, and draw a circle centered at point A. Without changing the compass opening, draw a circle centered at point B. The diagonals of a square bisect each other in mutually perpendicular. Let AB be the diagonal, when we draw a perpendicular to the diagonal AB the other two points of the square are in this perpendicular.And are in opposite sides.So we draw the two circles with same radius less than AB and greater than half of AB.

step-by-step explanation:

add the time and multiply by 2

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
