Question

The area of a triangle is 16 square units. The base of the triangle is x+4. The height of the triangle is x. Find x.

Answer 1

area of a triangle is

\(A=\frac{1}{2}bh \)

you have \(A=16, b=(x+4), h = x\).

Answer 2

plugging in we get \(16=\frac{1}{2}(x+4)x=\frac{1}{2}x^2+2x\)

can you solve \(\frac{1}{3}x^2+2x=16\)?

Answer 3

is 1/2 of x^2 just x?
