I beileve the answer is 5;4
No need to estimate. Its 19.8
The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5
<span>To get the Greatest Common Factor of 129 and 86 we need to factor each value first and then we choose all the copies of factors and multiply.</span>
The answer is 10.80. Hope this helps :)
