Lets write the information as an equation, and name x the number unknown: (x + 4)^2 = 36 that is: the sum of a number and 4: (x + 4) then, the square of <span>the sum of a number and 4: (x + 4)^2 so we have: </span>(x + 4)^2<span> = 36 </span>to solve we calculate square root to both sides of the equation: (x + 4)<span> = 6 </span>then we solve for x: x = 6 - 4 x = 2 so the unknown number is 2
Take the first point (2, 4) a scale factor of 3/2 will move the x coordinate 2 to 2*3/2 = 3 and the y coordinate 4 will be moved to 4*3/2 = 6. So the image of ( 2, 4) will be ( 3, 6) TH other verices will move in the same fashion.
