Answer: 25w+54
Step-by-step explanation:
Distribute:
=7w+(6)(3w)+(6)(9)
=7w+18w+54
Combine Like Terms:
=7w+18w+54
=(7w+18w)+(54)
=25w+54
Answer:
=25w+54
 
        
                    
             
        
        
        
<em><u>Question:</u></em>
Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of Q?
<em><u>Answer:</u></em>
x-coordinate of Q is 5
<em><u>Solution:</u></em>
Given that,
Point R divides in the ratio 1 : 3
Which means,
Point R divides the line segment PQ internally
The x-coordinate of the point which divides the line segment in ration m:n internally is given as:

Where,
 = x-coordinate of point dividing the segment R = -1
 = x-coordinate of point dividing the segment R = -1
 = x-coordinate of P = -3
 = x-coordinate of P = -3
 = x-coordinate of Q = ?
 = x-coordinate of Q = ?
m : n = 1 : 3
m = 1
n = 3
Therefore,

Thus x-coordinate of Q is 5
