First, let's convert X into 4

(3*4 - 4)ft, (4*2 - 1)ft, (2*4*2 - 15)ft

Now lets simplify this a little

(12 - 4)ft, (8 - 1)ft, (16 - 15)ft

Awesome now lets finish up

8 x 9 x 1 / 2 = 36

The answer should be 36ft. Unless I did my math wrong.

MrMuchimi

Answer:

179/180

Step-by-step explanation:

Step One

Find the prime factors of 18 and 20

18:3*3*2

20: 2 * 2 * 5

Step Two

You need two 2s two 3s and one 5 for the common denominator

The common denominator is 2 * 2 * 3 * 3 * 5 = 180

Step Three

Put the two fractions over 180

$\dfrac{17*10}{10*18} + \dfrac{1*9}{10*18}$

$\dfrac{170}{180} + \dfrac{9}{180}$
