Answer:

\boxed{\sf \cfrac{11}{5}\:\: or \:\: 2.2}

Step-by-step explanation:

\sf \left(\cfrac{-11}{20}\right)\div \left(\cfrac{-4}{16}\right)

Apply fraction rule:

\boxed{\sf\cfrac{a}{b}\div\cfrac{c}{d}  =\frac{a\times \:d}{b\times \:c}}

\longmapsto\sf \cfrac{-11\times \:16}{20\left(-4\right)}

Cancel the common factor of 16 and 20:

\longmapsto\sf \cfrac{-11\times4}{5\times(-4)}

Cancel common factor of 4 and  −4:

\longmapsto\sf \cfrac{-11}{5\times (-1)}

Multiply 5 by -1:

\longmapsto\sf \cfrac{-11}{-5}

Dividing two negative values gives a positive value:

\longmapsto\sf \cfrac{11}{5}

Or

\longmapsto\sf 2.2

Solve the following inequality: 3-5x-x^2&gt;=0
Dennis_Churaev [7]

Answer:

-5/2+-1/2√37≤x≤-5/2+1/2√37

Step-by-step explanation:

Step 1: Find the critical points

-x^2-5x+3=0

For this equation: a=-1, b=-5, c=3

−1x^2+−5x+3=0

x=−b±√b2−4ac/2a

x=−(−5)±√(−5)2−4(−1)(3)/2(-1)

x=5±√37 /−2

x=-5/2+1/2√37

Step 2: Check intervals in between critical points

x≤-5/2+1/2 √37 (Doesn't work in original inequality)

-5/2+-1/2√37≤x≤-5/2+1/2√37 (Works in original inequality)

x≥-5/2+1/2 √37 (Doesn't work in original inequality)

a rectangle plot measure 20ft. by 30ft. A 3-ft.-wide sidewalk surrounds it.Find the area of the sidewalk.
goldenfox [79]
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft

Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft

Area of the sidewalk = 759 - 600
A = 159 sq ft
