Answer: D) x+4+x+4
The two x terms combine to x+x = 2x
The other pair of like terms, the constants, add to 4+4 = 8
Overall we get 2x+8
2x+8 is also equivalent to 2(x+4) when you factor out the GCF 2.
The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
