I just know you can eliminate a which 18 degrees and c which is 61 degrees because m
The simplified form is 20x^2. Because you 2x*2, you get 4x. You multiply that by 5x, and then you get your answer.
It’s 45%
Explanation = 31900-22000/22000 • 100 = 45%
Hello,
2x²+x-14=0
Δ=1+4*14*2=113
x=(-1-√113)/4=-2,8839...≈-2.88
or x=(-1+√113)/4=2,40753≈2.41
