Answer:
3 and 4
Step-by-step explanation:
Well to start we have to know that they are asking us, a factorized form of a quadratic expression
a quadratic expression is of the form
ax ^ 2 + bx + c
Now the factored form is as follows
a ( x - x1 ) ( x - x2 )
Next, let's look at each of the options
In this case we lack a term with x since if we solve we have a linear equation
1. 5(x+9)
5x + 45
In this case if we pay attention they are being subtracted instead of multiplying, so we will not get a quadratic function
2. (x+4) - (x+6)
-2
In this case we have everything we need, now let's try to solve
3. (x-1) (x-1)
x^2 - x - x + 1
x^2 - 2x + 1 quadratic function
In this case we have everything we need, now let's try to solve
4. (x-3) (x+2)
x^2 -3x +2x -6
x^2 -x - 6 quadratic function
In this case we have a quadratic function but we do not have it in its factored form since we can observe the x ^ 2
5. x^2 + 8x
We have a
number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that
begins in -3 and closes in 8, that is,
<em>takes values from -3 to 8</em>. In a mathematical language this is given by
the following statement:

Answer:two dimensional shapes
Step-by-step explanation:
Answer:
The length is equal to 12 and the width is equal to 6.
Step-by-step explanation:
In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.
2L + 2W = P
2(2x) + 2(x) = P
4x + 2x = 36
6x = 36
x = 6
Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).
Your question would be clearer if written as "What is 145% of 6000?"
1.45(6000) = 8700
