To find this just put 8 over 20 because that is how many red pieces there are divide the equation and you will get 0.4 so I would say the answer is A.
Answers:
u = 18
v = 20
========================================================
Work Shown:
The leg YZ is congruent to the left FH
This means YZ = FH and that leads to u+v-18 = 10u-8v
The hypotenuse ZX is congruent to the hypotenuse HG
This means ZX = HG and we get the equation 14v-14u+32 = v+u+22
----------------------
The system of equations we have so far is
u+v-18 = 10u-8v
14v-14u+32 = v+u+22
Let's get the equations into standard form
Start with the first equation
u+v-18 = 10u-8v
u+v = 10u-8v+18
u+v-10u+8v = 18
-9u+9v = 18
-9(u-v) = 18
u-v = 18/(-9)
u-v = -2
Note how we can solve for the variable u to get
u = v-2
which we'll use later
----------------------
Let's get the other equation into standard form as well
14v-14u+32 = v+u+22
14v-14u-v-u = 22-32
-15u+13v = -10
Now plug in u = v-2 and solve for v
-15u+13v = -10
-15(v-2) + 13v = -10
-15v+30+13v = -10
-2v+30 = -10
-2v = -10-30
-2v = -40
v = -40/(-2)
v = 20
Which means,
u = v-2
u = 20-2
u = 18

Our functions are:
To solve this, we must use the expression g(-10) - f(3).
![-\frac{3}{2}(-10) + 12 - [-5(3)] + 12\\\\15 + 12 - [-5(3)] + 12\\\\15 + 12 - (-15) + 12\\\\27 - (-15) + 12\\\\42 + 12\\\\54](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B2%7D%28-10%29%20%2B%2012%20-%20%5B-5%283%29%5D%20%2B%2012%5C%5C%5C%5C15%20%2B%2012%20-%20%5B-5%283%29%5D%20%2B%2012%5C%5C%5C%5C15%20%2B%2012%20-%20%28-15%29%20%2B%2012%5C%5C%5C%5C27%20-%20%28-15%29%20%2B%2012%5C%5C%5C%5C42%20%2B%2012%5C%5C%5C%5C54)
The value of the expression g(-10) - f(3) is <em>15</em>.
