Construct equilateral triangle with sides, ABC such that AB = AC = CB = 10.5 cm. Measure and write down the size of angle < ABC.

Asquare is dilated by a scale factor of 1.25 to create a new square. how does the area of the new square compare with the area of the original square? a)the area of the new square is 1.25 times the area of the original square. b)the area of the new square is 2.50 times the area of the original square. c)the area of the new square is 1.252 times the area of the original square. d)the area of the new square is 1.253 times the area of the original square.

Which expression gives the area of the triangle shown below

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
