In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!
Thinks it b because it going to be a different size
Answer:
a = 2/3
Step-by-step explanation:
A cube root is the same as a 1/3 power. The square of that gives a 2/3 power.
a = 2/3

<em>Additional comment</em>
You can see the relationship between a root index and an exponent if you consider what the root means.
Consider a cube root, for example. When you cube the root, you get the original number:
(∛x)·(∛x)·(∛x) = x
Now, let's write the root as a power of x: x^a.
(x^a)·(x^a)·(x^a) = x . . . . . where x^a = ∛x
We know this product is ...
x^(a+a+a) = x^(3a) = x^1
This tells us that ...
3a = 1 ⇒ a = 1/3
That is, ∛x = x^(1/3).
Of course an n-th root is multiplied by itself n times to get the original number, so the corresponding exponent is x^(1/n).
Graphs of linear functions
Since we are graphing a line, if we have two points we can plot the whole line
We evaluate the line in two points in order to locate two places where it passes through. We say y = h(x)
1. If x = 0 then
h(x) = - 5(0) +3
= 0 + 3
= 3
Then y = 3
2. If x = 2 then
h(x) = - 5(2) +3
= -10 + 3
= -7
Then y = -7
Now, we have two points: (0, 3) and (2, -7)
We locate them and then we plot the only straight line that passes through both points
