Opening brackets gives;
4-8v=-8v+4
Putting like terms together;
4-4=-8v+8v
0=0
There is no solution thus.
12/-30=8x
cross multiply
12x=-240
x=-20
Substitute the value of the variable into the expression and simplify, its theta arrow-to-the-right, pi/4 times 1-tan theta/sin theta - cos theta (i cant type the signs on computer, sorry
Use math-way!!!!!!! I promise you won’t need to waist your points.%
The answer is 10.95445 and it is irrational because it is not a full square
