So the formula you need for this is
A=1/2bh
So count the squares on the outside of the bottom of the triangle and the left so that would be 7 and 7 so you multiply those together to get 49 then you would divide that answer by 2 and get 24.5 so your answer is 24.5 :)
Answer:
Step-by-step explanation:
To find the rate of change of a function, we are looking for it's slope.
We can find the slope of a line by seeing it's rise over run.
Basically - how much the line's y increases divided by how much the line's x increases.
We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is 
, however in this case it is -2 as we are dropping.
The change in x is 1 .
This means that the slope (rate of change) is 
.
Hope this helped!

Answer:
4ab² + 20b - 3a
Step-by-step explanation:
This question most likely asks us to simplify the expression, as factoring is not possible...
(ab² + 13b - 4a) + (3ab² + a + 7b),
ab² + 13b - 4a + 3ab² + a + 7b,
ab² + 3ab² + 13b + 7b - 4a + a,
Solution : 4ab² + 20b - 3a
