Which set of transformations would prove ΔGFE ~ ΔGHI? Translate ΔGHI by the rule (x − 2, y + 0), and reflect ΔG′H′I′ over x = −4. Reflect ΔGHI over x = −2, and translate ΔG′H′I′ by the rule (x − 2, y + 0). Translate ΔGHI by the rule (x + 0, y + 2), and dilate ΔG′H′I′ by a scale factor of 2 from point H. Reflect ΔGHI over x = −2, and dilate ΔG′H′I′ by a scale factor of 2 from point G.

it is 10.6 according to my calculations

i may be incorrect but i believe that her first error was in step one when she multiplyed her equation by 1/4 when she should have divided it by 1/4

the difference of two squares is a special form that has a factorization worth memorizing.

a² - b² = (a - b)(a + b)

your equation can be factored as

x² - 16 = 0

(x - 4)(x + 4) = 0

the zero product rule tells you the solutions are the values of x that make these factors zero: x=4, x=-4.
