The polygons in each pair are similar. Find the missing side length / first one has 4 &amp;x and second one has 12&amp;18
sergiy2304 [10]

Answer:

x = 6

Step-by-step explanation:

To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

\frac{4}{12}=\frac{x}{18}

Find x by cross multiplying numerator and denominator of each fraction.

4(18) = 12x

3/4w=9 what does w equal?
Studentka2010 [4]
3/4 w = 9

multiply by 4/3 on both sides

4/3 x 3/4 w = 9 x 4/3

w = 9 x 4/3

Simplify that

w = 3 x 4

w = 12

So your final answer is

\boxed{\bf{w=12}}
