ANSWER: 77
Explanation: Making 88 in 8 minutes means that the machine is making 11 per minute thus being said if the machine worked for 7 minutes it would make 77 pens. 
88/8=11 
11*7=77
        
             
        
        
        
Replace the x by x+3
so it would be
4log(x+3)
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Compare the ratios of the triangles like so:
Bigger to smaller

This statement is true. Both fractions simplified are equal to 1.5. Since they have the same ratios, they should be similar. 
 
        
             
        
        
        
Find the area of the larger rectangle. 
5 x 4 = 20  
One of the triangles is 2 x 2. Area of 2. Subtract 2 from 20.
20 - 2 = 18 
Another is 2 x 5. Area of 5. Subtract 5 from 18. 
18 - 5 = 13 
The last is 3 x 4. Area of 6. Subtract 6 from 13. 
13 - 6 = 7 
The area of the triangle QRS is A, 7. 
Hope this helps!
