Answer:
Step-by-step explanation:
(3x^2 + 2x - 3)(x-1)
Expanding the brackets
x(3x^2 +2x - 3) -1(3x^2 +2x -3)
3x^3 +2x^2 -3x -3x^2 -2x + 3
3x^3 - x^2 - 5x + 3
Answer:
x+14
Step-by-step explanation:
(12+x)+2
12+x+2
x+(12+2)
x+14
Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.
The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).
Pythagoras is in the form of;
a<em><u /></em>²+b²=c²
However, it can also be written in the form of c²=a²+b²
In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.
As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.
3²=9 and 4²=16.
As you're looking for C, you've got to add these together
9+16=25
As a²+b²=c², this means that the answer for C is the square root of 25.
√25= 5
Hope this has been able to help you :)
You'd have to draw a table of x and y values first to be able to graph.
Step 1: Pick any number for x. Let's pick 2.
Step 2: Plug in 2 into the equation: y = 2^2 + 2(2) - 3
Step 3: Solve for y: 4 + 4 - 3 = 5
Step 4: So the point (ordered pair) would be (x, y) ⇒ (2, 5). You can plot that on the graph.
Follow these steps 2 more times to get at least three ordered pairs.
Make sure you have enough points to know where the graph curves, then you can connect the dots and now there you have a graph and chart :)
0.41567 is:
... rational because it can be expressed as a fraction (e.g., 41567/100000)
... not irrational for the same reason
... not whole (obviously)
... not integer (obviously)
