we know that
A polynomial in the form is called a sum of cubes
so
Let's verify each case to determine the solution
<u>case A)</u>
we know that
-------> is not a perfect cube
therefore
the case A) is not a sum of cubes
<u>case B)</u>
we know that
-------> is not a perfect cube
-------> is not a perfect cube
therefore
the case B) is not a sum of cubes
<u>case C)</u>
we know that
-------> is not a perfect cube
therefore
the case C) is not a sum of cubes
<u>case A)</u>
we know that
Substitute
therefore
<u>the answer is</u>
is a sum of cubes
The total time to be invested to get a degree would be 630 hours
Total credits required = 180 credits
Number weeks In a quarter = 10 weeks
Number of credit earned per hour = 1 credit
To earn a degree :
Number of credits required per week :
180 / 10 = 18 credits per week
Since, credit is earned at a rate of 1 per hour ; then ;
Number of class hours per week = 18 hours per week.
This means 180 class hours is required.
For every class hour ; 2.5 hours is used for outside class study
Hence, Total outside class study hours will be :
(2.5 hours × 180 hours) = 450 hours
Therefore,
Total hours that would be invested :
(total outside class hours + tt’otal class hours)
(450 + 180) = 630 hours

Answer:
The solution of system of equation is (-2,0)
Step-by-step explanation:
Given system of equation are
Equation 1 : 2x+y=(-4)
Equation 2 : y+x=(-1)
To plot the equation of line, we need at least two points
For Equation 1 : 2x+y=(-4)
Let x=0
2x+y=(-4)
2(0)+y=(-4)
y=(-4)
Let x=1
2x+y=(-4)
2(1)+y=(-4)
y=(-6)
Therefore,
The required points for equation is (0,-4) and (1,-6)
For Equation 2 : y+x=(-1)
Let x=0
y+x=(-1)
y+(0)=(-1)
y=(-1)
Let x=2
y+x=(-1)
y+(2)=(-1)
y=(-2)
The required points for equation is (0,-1) and (2,-2)
Now, plot the graph using this points
From the graph,
The red line is equation 1 and blue line is equation 2
Since. The point of intersection is solution of system of equations
The solution of system of equation is (-2,0)
