Here's a diagram showing how to combine angles LDA (in red) and angle ADE (in blue). Hopefully it becomes a bit clearer why these two angles add up to line segment LE. Erase the shared segment DA if it helps show LE better.

See attached image below.

Use completing the square to find the value to add that makes x^2 - 12x a perfect square trinomial. Then write the expression as

yarga [219]

Answer:

Step-by-step explanation:

If you want to make

$x^2-12x$

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

$(x^2-12x+36)-->(x-6)^2$

What should be the top item on a list of your life goals? A. A goal that's financially feasible B. A goal that's most important

Feliz [49]

The top item on a list of your life goals should be B. a goal that's most important to you. You shouldn't care much for what other people want from you - if you know what you want and need, you should make that your priority and try to achieve your life goals. It doesnt matter whether you can manage that financially, or whether it's going to be easy - if you really want it, you are going to try your best in order to achieve it.
