Answer:
3x² - 12x + 13
Step-by-step explanation:
given
f(x) = 3(x - 2)² + 1 ← expand (x - 2)²
= 3(x² - 4x + 4) + 1
= 3x² - 12x + 12 + 1
= 3x² - 12x + 13 ← in standard form
Answer:
Approximately 439.6 square millimeters.
Step-by-step explanation:
The formula for the surface area of a cone is the following:

Where, <em>r </em>is the radius and <em>l</em> is the slant height.
The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:

first of all the brace and x or / before + or -
3x4=12
8-12=-4 => first part
54/6=9
9+2=11 => second part
11x(-4)=-44
