Question

If a triangle, has an area of 4x+8 and a height of 8, write an expression to represent the base. The base of the triangle is ?

Answer 1

we know that the area of a triangle is:

`A=(h\cdot b)/(2)`

so we replace the values of the area so:

`4x+8=(8b)/(2)`

and we solve for x

`\begin{gathered} 8x+16=8b \\ b=x+2 \end{gathered}`
