Help please with this one

evablogger [386]

Answer: 10.20 yd

<u>Step-by-step explanation:</u>

h² + 5h - 155 = 0

a=1 b=5 c=-155

$x = \frac{-b +/- \sqrt{b^{2}-4ac}}{2a}$

$h = \frac{-5 +/- \sqrt{5^{2}-4(1)(-155)}}{2(1)}$

$h = \frac{-5 +/- \sqrt{25+620}}{2}$

$h = \frac{-5 +/- \sqrt{645}}{2}$

$h = \frac{-5 +/- 25.40}{2}$

$h = \frac{-5 +25.40}{2}$ , $h = \frac{-5 - 25.40}{2}$

$h = \frac{20.40}{2}$ , $h = \frac{-30.40}{2}$

h = 10.20 h = -15.20 (height can't be negative)
