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

Answer 1

Algebra! Translate "3cm greater than 5 times the height" into b=5h+3, where b is the base and h is the height.
Now suppose h=the height=6 cm. Calculate the base.
What is the formula for the area of a triangle when the base and height are known?

Answer 2

I'm so confused. haha, im sorry, i must be a pain... >.<

Answer 3

"a base of 3 cm greater than 5 times its height" is practically an invitation to choose variables and then represent the relationship between base and height algebraically. This is one of the foundation stones of algebra.
I use b for base and h for height. I derive a formula for b in terms of h by translating those words into symbols: a base of 3 cm greater than 5 times its height => b=5h+3.

OK: if h is 6cm, b=5(6cm)+3cm= ???

Answer 4

5(6cm)+3cm= 33 cm?
