Answer:
x = 4 or x = -3
Step-by-step explanation:

Take square both the sides,

x² - x - 12 = 0
x² - 4x + 3x - 3*4 =0
x*(x - 4) + 3*(x - 4)= 0
(x- 4 )(x+3) =0
x -4 =0 or x + 3 = 0
x = 4 or x = -3
Answer:
4695.90
Step-by-step explanation:
The exponential growth function is given as:
y = a(1 + r)^t
a = Initial value = 390
y = Value after time t = ?
r = Growth rate = 5% = 0.05
t = Time in years =51
Hence
y = 390(1 + 0.05)⁵¹
y = 4695.9002123
Approximately = 4695.90
3 / 4 w + 8 = 1 / 3 w - 7
Multiply by LCD = 4 ( w + 2 )(3w - 7)
3(3w-7) = 4(w + 2)
3*3w - 3*7 = 4 * w + 4 * 2
9 w - 21 = 4 w + 8
Add 21 to both sides :
9w - 21 + 21 = 4w + 8+ 21
9w = 4w + 29
9w - 4w = 29
5 w = 29
Divide both sides by 5 :
5 w / 5 = 29 / 5
w = 29 / 5
