Answer:

Height = 40 cm

Step-by-step explanation:

Volume is length x height x width.

You are given Volume, Length and width, so we multiply the length and width together then divide the volume by that to find the height.

Length x width = 25 * 10 = 250 square cm.

Height = 10,000 cm^3 / 250 cm^2

Height = 40 cm

Logarithms <br> 8^(x-9) = 19^(3x+2)

Sophie [7]

$\bf 8^{x-9}=19^{3x+2}\implies log(8^{x-9})=log(19^{3x+2})
\\\\\\
(x-9)log(8)=(3x+2)log(19)\impliedby distributing
\\\\\\
xlog(8)-9log(8)=3xlog(19)+2log(19)
\\\\\\
xlog(8)-3xlog(19)=9log(8)+2log(19)\impliedby \textit{common factor}
\\\\\\
x[log(8)-3log(19)]=9log(8)+2log(19)
\\\\\\
x=\cfrac{9log(8)+2log(19)}{log(8)-3log(19)}$
