The sizes of the angles, in degrees, of a triangle are 2x+9, x+13 and x-8 Work out the value of x

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters .

What are “like terms”? why can we only add like terms?

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
