Which of the following is one solution to the expression (ax + b)(cx - d) = 0 ?

V125BC [204]

We know that
if (ax + b)(cx - d) = 0
then
(ax + b)= 0-----> ax=-b------> x=-b/a
and
(cx - d) = 0-----> cx=d------> x=d/c

therefore

the answer is the option
C. -\frac{b}{a}

GI = 6, HI = 8, DT = 12, what is IE? a.12 b.16 c.8 d.4

harina [27]

Answer:

Option D

Step-by-step explanation:

By the property of intersecting chords,

If two chords are intersecting at a point inside a circle, product of lengths of the line segments on each chord is equal.

DI × EI = HI × GI

12 × EI = 8 × 6

EI = $\frac{48}{12}$

EI = 4

Therefore, Option D is the correct option.
