Reflection of any polygon does not affects its length.

As it is given both polygons are reflection of each other so their sides are congruent.

AB ≅ EF = 3 units

BC ≅ FG = 2 units

CD ≅ GH = 2.2 units

DA ≅ HE = 3.2 units

What is y=X2-6x+7 in vertex form

alina1380 [7]

Answer:

$y = (x - 3^{2}) - 2$

Step-by-step explanation:

$y = a (x - h)^{2} + k$

Standard form: $y = ax^{2} + bx = c$

Our vertex is: $xvertex = - \frac{b}{2a} \\y = x^{2} - 6x + 7 ( STANDARD - FORM)\\$

Finally we get $y = (x - 3^{2}) - 2$ as our answer.

Have an amazing day!
