Answer:
19. 16x-4 ; 20. 10y+1
Step-by-Step explanation:
19. The perimeter of a rectangle is expressed as P= 2(side1) + 2(side2)
If side1= x-3 and side2= 7x+1
P=2(x-3) + 2(7x+1)
=(2x-6) + (14x+2)
P=16x-4
or
P=4(4x-1)
20. The perimeter of a triangle is expressed by adding all three sides together.
If side1=3y+5 side2=y-4 side3=6y
P=(3y+5)+(y-4)+(6y)
P=10y+1
The answer would be <span>6.5.12
A triangle couldn't be made if the total sum of the two shortest side is less than the longest side. In this case, the two shortest side would be 5 and 6. The longest side would be 12.
If you try to add the two lowest side, the result would be 5+6=11. That means even if you make the triangle with 179.99 degrees that the 5 and 6 look like a straight line, the longest side it can achieve is 11.</span>
