the length of a rectangle is 2 cm less than five times the width. the area of the rectangle is 16 cm^2. find the length and widt
ahrayia [7]
<span>length = L
</span>width = w

L = (5w-2) cm

w(5w-2)=16 \\ 5w^2-2w-16=0 \\ D=b^2-4ac=(-2)^2-4*5*(-16)=324 \\ w_{1,2}= \frac{-bб \sqrt{D} }{2a}  \\ w_1= \frac{2- \sqrt{324} }{2*5}= \frac{2-18}{10}=-1.6 \ \ \O \\ w_2=  \frac{2+18}{10}=2 cm

width = 2 cm
length = 5w-2 = 5*2-2 = 8 cm

How do I simplify this radical expression? I'm supposed to divide by rationalizing the denominator.
kotegsom [21]
In short, you use 1, since any number is itself times 1, or whatever = whatever * 1

\bf \cfrac{4}{\sqrt{50}}\iff \cfrac{4}{\sqrt{50}}\cdot 1\iff \cfrac{4}{\sqrt{50}}\cdot \cfrac{1}{1}\implies \cfrac{4}{\sqrt{50}}\cdot \cfrac{\sqrt{50}}{\sqrt{50}}&#10;\\\\\\&#10;\cfrac{4\sqrt{50}}{\sqrt{50^2}}\implies \cfrac{4\sqrt{50}}{50}
