Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
Y=X
7x + (2x+27)=180-> 9x= 180-27 -> x=17
-30 (2w + 3) is the only one I can figure out.
I hope this helped tho!! :]
x = 75 degrees
180 - 125 = 55
50 + 55 = 105
180 - 105 = 75
