Answer:
0.375x^2
Step-by-step explanation:
(-1.5x)(-0.25x)
= (-1.5)(0.25)(x)(x)
= 0.375x^2
Answer:

Step-by-step explanation:
Given
Let the angle be 

is co-terminal with -5
Required
Find 
Start by dividing 5 by 360 (ignore the negative)

The nearest integer greater than 0.0138 is 1.
<em>This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time</em>
So,
is calculated as:



Answer:
1. 2x+8
2. 3x-6
3. -6x-3
Step-by-step explanation:
I dunno what you're supposed to do for the modeling, but I simplified the expressions
Answer:
2) a trapezoid
Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram.
For this case we have the following system of equations:

Substituting the second equation into the first we have:

The equality is not fulfilled, therefore the system has no solution.
The lines do not intersect.
Answer:
The system has no solution.
