Assuming it equals 0
for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

given
5x^2+2x-3=0
a=5
b=2
c=-3

x=\frac{-2+/- \sqrt{2^2-4(5)(-3)} }{2(5)}
x=\frac{-2+/- \sqrt{4+60} }{10}
x=\frac{-2+/- \sqrt{64} }{10}
x=\frac{-2+/- 8 }{10}
x=(-2+8)/10 or (-2-8)/10
x=6/10 or -10/10
x=3/5 or -1

Hey there! :D

When there are two lines (parallel) that are cut by a transversal, corresponding angles form. These are angles that are in the same position on the same side. m<2 is corresponding to the angle that equals 38 degrees. They are congruent and have the same measure. 

m<2= 38 degrees 

Remember, this only works because the problem said that line L and M are parallel.

I hope this helps!

Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey
shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)


as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8


the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6
