Answer:

x = 2 and x = 10

Step-by-step explanation:

(x+3)^2 = (x - 5)^2 + (x + 2)^2

x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4

x^2 + 6x + 9 =2x^2 - 6x + 29

x^2 - 12x + 20 = 0

(x - 10)(x - 2) = 0

x - 10 = 0; x = 10

x - 2 = 0; x = 2

Answer:

- 2.71

Step-by-step explanation:

2· $4^{v + 4}$ + 20 = 32
2· $4^{v + 4}$ = 12
$4^{v + 4}$ = 6
(v + 4) log 4 = log 6
v + 4 = log 6 / log 4
v + 4 = 1.29 (<em>rounded</em>)
v = 1.29 - 4
v = - 2.71
