Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student
Now left student = 10 -1 = 9
So number of ways to assigned double student
Now left student = 9-2 = 7
So number of ways to assigned triple student =70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Use the Product Rule: x^ax^b = x^a + b
3x^-4 + 1 - 5 - 3(5x^-2x + 1)
Simplify -4 + 1 to -3
3x^-3 - 5 - 3(5x^-2x + 1)
Use the Product Rule: x^a x^b = x^a + b
3x^-3 - 5 - 3(5x^-2 + 1 + 1)
Simplify -2 + 1 to -1
<u>3x^-3 - 5 - 3(5x^-1 + 1)</u>
Answer:
The value of x =10°
Step-by-step explanation:
Check attachment for solution.
Triangle theorem: the sum of the opposite interior angle is equal to the exterior angle.
<JKL+<LJK=<KLM
2x+14+3x+15=7x+9
Collect like terms
2x+3x-7x=9-14-15
-2x=-20
Divide both side by -2
x=10°
