Question

what is a function rule for the are of a triangle with a base 3 cm greater than 5 times its height. what is the area of the triangle when its height is 6cm ?

Answer 1

So you know the area of a triangle is \[A=\frac{ bh }{ 2 }\]

Answer 2

So the base is 3 cm greater than 5 times the height of the triangle

Answer 3

Translating this to mathese, the base=3+5h

Answer 4

Now we can write the base in terms of h, and rewrite our equation

Answer 5

\[A \frac{ h(3h+5) }{ 2 }\]

Answer 6

whoops missed an equal sign should be a= the rest of it

Answer 7

oh i get it

Answer 8

So if you want to distribute the h, you would now get \[A=\frac{ 3h ^{2} +5h}{ 2 }\]
