Answer:
87/3
Step-by-step explanation:
Here we are given the expression:

Now we have to find the value of this expression when x equals 9.
So plugging the value of x as -9 in the given expression:


=87/3
So on evaluating we get the value of expression as 87/3.
The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.
We can set two of the equations to equal each other and solve for x:
3x -5 = 2x +20
Add 5 to each side:
3x = 2x +25
Subtract 2x from each side:
x = 25
