Just double 18.75 because the total area needed to cover is 2 square meters
That sentence is confusing...
That sentence is confusing...
There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:
Cos(90)=0 or Cos(0)=1... Both are correct options...
If your teacher wrote that, he doesn't know to write very good...
Good luck!

Answer:
Step-by-step explanation:
Given the simultaneous equation
2x - y = 11. Equation 1
6x – 3y = 15. Equation 2
Using elimination method
Multiply the coefficient of x in equation 1 (which is 2) to equation 2. Also, multiply the coefficient of x in equation 2 (which 6) to equation 1. By doing this we are going to eliminate x
2x - y = 11. × 6 Equation 1
6x – 3y = 15. ×2 Equation 2
12x-6y=66. Equation 3
12x-6y=30. Equation 4
Subtract equation 4 from 3
Then (12x-6y) - (12x-6y) =66 -30
0=36
Which is not possible
Then the system has no solution, it has no solution at all. Because 0 is not equal to 36. If has been 0 equals to 0, then we may many solutions for simultaneous equation.
