Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.
152 miles
Ratios:
They got smaller
y = 0.714 x -5
at x =0, y = -5, means the constant is -5
at x= -7 y= -8,
-8= -7a -5
a=0.714
7√5
3√5 + 4√5
= 7√5
m=-2
