Without multiplying, determine the sign of the product (356,864)(−194,758). The sign of the product is positive because a positive multiplied by a negative is a positive. The sign of the product is negative because a positive multiplied by a negative is a negative. The sign of the product is negative because the second number is negative. The sign of the product is positive because the first number is positive.

A cube has a volume of 729 cubic centimeters. What can be concluded about the cube? Check all that apply. Recall the formula mr021-1.jpg. The side length, s, can be found using the equation mr021-2.jpg This is a perfect cube. The side length is 243 centimeters. The side length is 9 centimeters. Taking the cube root of the volume will determine the side length. If you multiply the volume by three, you can determine the side length.

What are the steps for using a compass and straightedge to construct a square? Drag and drop the steps in order from start to finish.1.Construct a line perpendicular to line m through point F. Label a point on this line as point G.2.Use a straightedge to draw line m and label a point on the line as point F.3.Without changing the compass width, place the compass point on point H and draw an arc in the interior of ∠HFK .4.Use the straightedge to draw JH¯¯¯¯¯ and JK¯¯¯¯¯.5.With the compass open to the desired side length of the square, place the compass point on point F and draw an arc on line m and an arc on FG←→ . Label the points of intersection as points H and K.6.Keeping the same compass width, place the compass on point K and draw an arc in the interior of ∠HFK to intersect the previously drawn arc. Label the point of intersection as point J.
