Answer 2

Answer:

$x = 3.7931034483$

Step-by-step explanation:

= 4x(5x+14) + (-5) 5x+14) = 180

$20x {}^{2} + 56x + \: 25x + 70 = 180$

$20x {}^{2} + 81x + 70 = 180$

$20x {}^{2} + 81x = 180 - 70$

$20x {}^{2} + 81x = 110$

$20x {}^{2} + (9x) {}^{2} = 110$

$power \: \: are \: \: equal$

$20x + 9x = 110$

$29x = 110$

$x = 110 \div 29$

$x = 3.7931034483$
