If the area of a square is numerically twice the perimeter of that square, what is the side of the square?

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

If two angles of a triangle have equal measures and the third angle measures 90°, what are the angle measures of the triangle? a. 60°, 60°, 60° b. 45°, 90°, 90° c. 30°, 30°, 90° d. 45°, 45°, 90°
