Question

9. Find the area of the triangle. A = 1/2 b h. Simplify to the simplest polynomial form.

Answer 1

so its

\[\frac{1}{2} \times (2x + 2) (7x - 3)\]

factorise 2x + 2 = 2(x + 1) so the equation is

\[A = \frac{1}{2} \times 2(x + 1)\times (7x - 3)\]

will give

\[A = (x + 1)(7x - 3)\]

all you need to do is distribute to find the area equation.

Answer 2

Thank you. I go it.
