A soccer team made 76 penalty shots out of 100.Which ratio represents successful penalty shots to missed penalty shots?
almond37 [142]
Sense we are wanting to find <u>how many were miss</u>, then, we are practically going to subtract the following:

\boxed{76-100}= \     \left[\begin{array}{ccc}\bf{24\end{array}\right]

So, from this begin understood, we would then combine both the penalties that were shotted, to the onces that weren't.

So, b subtracting these both, we would grab the result, and then smash that with the number of the penalties that were made in.

Your answer: \boxed{\bf{76:24}}

Answer: (x−2)(x−2)

The middle number is -4 and the last number is 4.

Factoring means we want something like

Can you think of the two numbers?

Try -2 and -2:

-2+-2 = -4

-2*-2 = 4

Fill in the blanks in

(x+_)(x+_)

with -2 and -2 to get...
