<span>let's analyze two cases
</span>
case A) <span>2(√x)−4=10
2</span>√x=10+4----> 2√x=14----> √x=14/2----> square---> x=7²----> x=49

case B)
2√(x-4)=10
√(x-4)=10/2-----> square---> x-4=5²----> x=25+4-----> x=29

Work out the area of the rectangle give your answer as a mixed number

AlladinOne [14]

We'll first convert the mixed fractions to "improper" and then get their product, since the area of a rectangle is the product of its length and width.

$\bf \stackrel{mixed}{5\frac{1}{6}}\implies \cfrac{5\cdot 6+1}{6}\implies \stackrel{improper}{\cfrac{31}{6}}
\\\\\\
\stackrel{mixed}{2\frac{2}{7}}\implies \cfrac{2\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{16}{7}}
\\\\\\
\cfrac{31}{6}\cdot \cfrac{16}{7}\implies \cfrac{496}{42}\implies \stackrel{simplified}{\cfrac{248}{21}}\implies 11\frac{17}{21}$
