Step-by-step explanation:

= ( -  \frac{1}{3}  +  \frac{1}{9} ). {4}^{2}  +  \frac{5}{18}

= ( -  \frac{3}{9}  +  \frac{1}{9} ).16 +  \frac{5}{18}

=  -  \frac{2}{9} .16 +  \frac{5}{18}

=  -  \frac{32}{9}  +  \frac{5}{18}

=  -  \frac{64}{18}  +  \frac{5}{18}

=  -  \frac{59}{18}

Change the fraction w-3/w+5 into an equivalent fraction with the denominator w2 + w – 20.
viktelen [127]
ANSWER

\frac{ {w}^{2}  - 7w + 12}{ {w}^{2}  + w - 20 }

EXPLANATION


The given fraction is,

\frac{w - 3}{w + 5}

To get an equivalent fraction, we multiply both the numerator and the denominator by the same quantity that will give us

w²+w-20

in the denominator.


This implies that,

\frac{w - 3}{w + 5}  =  \frac{(w - 3)(w - 4)}{(w + 5)(w - 4)}

We multiply out the numerators and denominators using the distributive property to obtain,


\frac{w - 3}{w + 5}  =  \frac{ {w}^{2}  - 4w - 3w + 12}{ {w}^{2} - 4w + 5w - 20 }

This simplifies to

\frac{w - 3}{w + 5}  =  \frac{ {w}^{2}  - 7w + 12}{ {w}^{2}  + w - 20 }

Whats the area of this shape
forsale [732]
First cut the shape into a square, triangle and rectangle. Then add all 3 areas. Area of a quadrilateral is A= b x h So once square is 4 X 4= 16. The rectangle has a area of 4 x 2= 8. The triangle, using the formula 1/2bh has an area of 1/2 x 2 x 4 = 4. So the area of the shape is 16 + 8 + 4 = 28 units
