Answer:
h = 2A/b
Step-by-step explanation:
The given area triangle is denoted by:
A=1/2bh
By solving for "h", we're simply asked to make "h" the subject of the formula, that is putting "h" on one side of the equation and all other variable/values on the other side of the equation.
By doing this, we move other variables presently on the right side with "h" and the left hand side of the equation takes them all except "h", then we have:
2A/b = h.
In this question, you would be solving the expression by combining like terms.
Solve:
(5a + 3b - 6c) - (20 - 4b + 13c)
Distribute the negative to the variables inside the parenthesis.
5a + 3b - 6c - 20 + 4b - 13c
Combine like terms.
5a + 7b - 6c - 20 - 13c
5a + 7b - 19c - 20
You can't combine anymore like terms now, so your answer would be 5a + 7b - 19c - 20
Answer:
5a + 7b - 19c - 20
It seems as if it adds 2 blocks to the bottom end each time, and 1 to the top.
So, it would be a t-shape with those rules

do the parentheses in the parentheses first, then the outer parentheses, then the stuff outside the parentheses.
