Answer:
x=5 and x=-11
Step-by-step explanation:
(x-2)(x+8)=39
Subtract 39 from both sides
Factor:
(x-5)(x+11)=0
Set factors to 0.
x-5 =0
x+11 =0
x=5, x=-11
Simple answer it equals -15 just fill it in and multiply the variable to the whole number on each side then subtract hope I helped :)
Answer:
6.67 feet
Step-by-step explanation:
The situation is as shown in the figure.
ON is the normal to the mirror at the point of incidence O
⇒ ∠BON = ∠DON = 90°
By the laws of reflection: angle of incidence = angle of reflection :
∠AON = ∠CON
⇒ ∠AOB = ∠COD
⇒tan(∠AOB) = tan(∠COD)
⇒ =
⇒ =
⇒x = = = 6.67 ft
∴ Distance of the mirror from basketball goal is 6.67 ft
