Using the integer rule 1/ (xⁿ) = x^-n question becomes ∫(4x - 2(x^-3)) dx

Then using the formula ∫xⁿ dx = (xⁿ⁺¹)/n+1 and assuming there may be a...

180-140=40 

40/2 =20

each other angle is 20 degrees

To solve this question you need to rearrange the equation to obtain an expression in the form ax=. Make sure that whatever you do the one side of the = sign, you must also do to the other side. Firstly, s...

x=3, y=-7, z=2

Golden rule: Do the Same thing to both sides of the equation Approach in 4 steps 1) Multiply out any brackets 2) Gather the like terms (Use analogy of apples and oranges) 3) Get all unknown terms to one s...
