2x² + 4x + 4 + x² + 1 = 180

Tasya [4]

Step-by-step explanation:

$2 {x}^{2} + 4x + 4 + {x}^{2} + 1 = 180$

$3 {x}^{2} + 4x + 5 = 180$

${3x}^{2} + 25x - 21x - 175 = 0$

$x \times (3x + 25) - 7(3x + 25) = 0$

$(3x + 25) \times (x - 7) = 0$

$3x + 25 = 0 = x - 7 = 0$

$x = - \frac{25}{3} = x = 7$

$= x_{1} = - \frac{25}{3} . \: \: x_{2} = 7$

What's the correct choice please help

nadezda [96]

Answer:

$77,886

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

The table states that:

$201.6 in 2006 is worth $232.957 in 2013.

We want to find:

The value of $90,000 in 2013 in 2006:

$201.6 - $232.957

x - $90000

Applying cross multiplication

$232957x = 201.6*90000$

$x = \frac{201.6*90000}{232957}$

$x = 77886$

$77,886 is the answer
