I am confused on this quadratic problem.

1 answer:

5 0

Answer:

(x+5)^2=81 would be correct

Step-by-step explanation:

solution (if you want it)

x² + 10x + 25 = 81

x² + 10x - 56 = 0

(x + 14)(x - 4) = 0

x = 4, x = -14

Use Pythagoras theorem

25^2 = 24^2 + x^2

x^2 = 25^2 - 24^2

x^2 = 49
x = 7 feet Answer

Answer:

$A)~ 2(x+2)=2x+14~(NO)$

$B)~14(x+3)=14x+42~(YES)$

$C)~14(x+5)=14x+70~(NO)$

$D)~7(2x+6)=14x+42~(YES)$

$E)~2(2x+20)=14x+40~(NO)$

$So,~ B ~and ~ D ~ are~ your ~ answers$
