Answer:

Step-by-step explanation:
we know that
The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle
Let
x-----> the area of square
y----> the area of rectangle
P -----> the probability

<em>Find the area of square (x)</em>

<em>Find the area of rectangle (y)</em>

Find the probability P

 
        
             
        
        
        
The answer is v= -8x/-xy+9
Here is the step by step process (This is going to be long):
1.  9v+8x=vxy
Multiply both sides by vx
2.  9v+8x+−vxy=vxy+−vxy
−vxy+9v+8x=0
Add -vxy to both sides
3.  −vxy+9v+8x+−8x=0+−8x
−vxy+9v=−8x
Add -8x to both sides
4.  v(−xy+9)=−8x
Factor out the variable v
5.  v(-xy+9)/-xy+9 = -8x/-xy+9
v = -8x/-xy+9
Divide both sides by -xy+9
 
        
             
        
        
        
Answer:
A = x^2 + 4x -21
Step-by-step explanation:
L = x+7
W = x-3
A = L*W
A = (x+7)(x-3)
A = x^2 + 4x - 21
 
        
             
        
        
        
Step 1     
<u>Find the value of TS</u>
we know that
if PQ is parallel to RS. then triangles TRS and TPQ are similar
so

solve for TS

we have


substitute
 
  

Step 2
<u>Find the value of SQ</u>
we know that

we have


substitute

therefore
<u>the answer is</u>
the value of SQ is
