Answer:

Step-by-step explanation:

So you basically replace the x with 2. So f(x) = x21, then it would change to f(2) = 2(21). Then you would just multiply 21 by 2 and you would get 42.

Hope this helps!

Answer:

$a=22.5\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

In this problem

If polygon RSUPE is similar to polygon KQUIC

then

$\frac{RS}{KQ}=\frac{RE}{KC}$

substitutes the values and solve for a

$\frac{a+2}{14}=\frac{17.5}{10}\\ \\10a+20=14*17.5\\ \\10a=245-20\\ \\a=225/10\\ \\a=22.5\ units$
