5 and -7 are the solutions to (x-5) (x+7) =12

konstantin123 [22]

Answer: No

Step-by-step explanation:

$(x-5)(x+7)=12$

Replace x for 5 and -7 separately.

$(5-5)(5+7)=12\\0(12)=12\\0=12$

$(-7-5)(-7+7)=12\\-12(0)=12\\0=12$

How do I solve for x

skad [1K]

Answer:

Step-by-step explanation:

Look at the picture.

If ABC is any triangle and AD bisects (cuts in half) the angle BAC, then

$\dfrac{AB}{BD}=\dfrac{AC}{DC}$

In our triangle we have the proportion:

$\dfrac{x}{8}=\dfrac{10-x}{6}$ <em>cross multiply</em>

$6x=8(10-x)$ <em>use distributive property</em>

$6x=(8)(10)+(8)(-x)$

$6x=80-8x$ <em>add 8x to both sides</em>

$14x=80$ <em>divide both sides by 14</em>

$x=\dfrac{80}{14}$

$\boxed{x=\dfrac{40}{7}}$
