A

Step-by-step explanation:

4x^2-8x-60=0

a=4 b=-8 c=-60

*I am going to plug these numbers into the quadratic formula*

x=-(-8)plus or minus

*simplified into...

x=-8 plus or minus

x=5 or x=-3

pls mark me brainliest

what are the statments

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
