When you have something multiplied by more than one term in parentheses, you multiply that something (in this case 6) by both terms (x and y). 
6x+6y+x+y. Add like-terms. 7x+7y

Answer:
5) p=67.5
6) p=60.9
Step-by-step explanation:
To find the perimeter of a polygon you add all the side lengths together.
Step 1:
11.3+11.3+23.3+21.6=67.5
Step 2: 
19.7+14+9.3+17.9=60.9
 
        
                    
             
        
        
        
The slope is given as m = 7m=7 and the yy-intercept as b = - \,4b=−4. Substituting into the slope-intercept formula y = mx + by=mx+b, we have
since m=7 and b=-4, we can substitute that into the slope-intercept form of a line to get y=mx+b → y=7x-4
The slope is positive thus the line is increasing or rising from left to right, but passing through the yy-axis at point \left( {0, - \,4} \right)(0,−4).
