Solve the equation by using the quadratic formula.

4x^2 − 7x + 3 = 0
question 4 options:

a.8 & 6

b.1 & 3/4

c.4 & 3

d.8 & 6/8

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
