AACB = ADCE. If<br> AC = 5 and BC = 7<br> CD = [ ? ).<br> PLS HELP LOL PLS
FromTheMoon [43]

Answer:

CD = 5

Step-by-step explanation:

AC = 5

BC = 7

∆ACB ≅ ∆DCE, therefore,

AC = CD,

BC = CE, and,

AB = DE

Thus,

AC = CD = 5

CD = 5

How do you factor: x^2-4x+2xy-8y?
hoa [83]

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

(x^{2}−4x)+2xy−8y

Factor out the greatest common factor (GCF) from each group.

x(x−4)+2y(x−4)

Factor the polynomial by factoring out the greatest common factor,  x−4.

(x−4)(x+2y)

I believe this is correct. Good luck.
