Hello,
f(x)=7x²+42x=7(x²+2*3x+9)-63=7(x+3)²-63.
Answer: What is the formula for finding the area of a triangle?
Not technically, but sometimes you may have to find the height using the Pythagorean Theorem, so if you have the hypotenuse and the base of a right triangle, the height, h = √(c^2 - b^2), so the area of the triangle could be found by A = 1/2 b √(c^2 - b^2), but it is the same principle as A = 1/2 b h.
