Answer:

x = 8 units

Step-by-step explanation:

Note that the ratio of the middle-length legs is 12/18, and that of the shortest-length legs is x/12.

Then:

12        x

----- = -----

18       12

... which, through cross- multiplication, becomes 18x = 144.  Then x = 8 units

What the answer for 1/4 x 12
coldgirl [10]
Treat 12 as 12/1 that means 12 divided into 1 part
1/4 times 12/1

multiply the top and the bottom becuase

\frac{x}{y} times \frac{z}{t} = \frac{x times z}{y times t} so

1/4 times 12/1=(1 times 12)/(4 times 1)=12/4=3/1=3

A circle cuts the x-axis at (4,0) and (14,0), and cuts the y-axis at (0,6) and (0,8). Find it's equation
gayaneshka [121]
It is not a circle but you can find the equation of the ellipse.
To do this we need to work out the major and minor radii and the centre
The centre is at (9, 7)
The major (y) radius is 1 and the minor (x) radius is 5
Therefore the equation is (x-9)/5 + (y-7)/1 = 1
