6 0

Answer:

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

Step-by-step explanation:

x=  −b±√b2−4ac /2a

x= −(1)±√(1)2−4(−2)(8) /2(−2)

x= −1±√65 /−4

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

Find the length of AD.
Sophie [7]

Answer:

AD = 4.5

Step-by-step explanation:

Since DE is parallel to AC and intersects 2 sides of the triangle it divides those sides in proportion, that is

\frac{BD}{AD} = \frac{BE}{EC} , substitute values

\frac{3}{AD } = \frac{8}{12} ( cross- multiply )

8AD = 36 ( divide both sides by 8 )

AD = 4.5
