Find the area of the triangle please I need help really bad I don't understand this help​
vivado [14]

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 :)

PLZ HELP only got 30 minutes left will brainliest. What is the rate of change of the function? –2 --1/2 1/2 2
Helga [31]

Answer:

-2

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 1 - (-1) = 2, 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 \frac{-2}{1} = -2.

Hope this helped!

(ab² + 13b - 4a) + (3ab² + a +7b)
Natalija [7]

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
