Since the formula for the area of a circle is Pi x r squared, the area would be 81 x Pi (you teacher may want you to use Pi as 3.14 or put it in your calculator).

Simplify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?

andrew11 [14]

For this case we must simplify the following expression:

$-3 (x + 3) ^ 2-3 + 3x$

We solve the parenthesis:

$-3 (x ^ 2 + 2 (x) (3) + 3 ^ 2) -3 + 3x =\\-3 (x ^ 2 + 6x + 9) -3 + 3x =$

We apply distributive property to the terms within parentheses:

$-3x ^ 2-18x-27-3 + 3x =$

We add similar terms:

$-3x ^ 2-18x + 3x-27-3 =\\-3x ^ 2-15x-30$

Answer:

$-3x ^ 2-15x-30$
