add on to question: image is a right triangle sides : 8√7+ 4√63+ 6√28

yoursopretty:) · Answer

my answer: Adding all the sides together: 8√7+ 4√63+ 6√28simplify breaking down numbers inside the radical: 8√7 + 4√9x7 + 6√4x7simplify by putting simplified numbers outside the radical: 8√7 + 4x3√7 + 6x2√7multiplying the numbers outside the radical: 8√7 + 12√7 + 12√7combine like terms: 8+12+12 7+7+7 = 32√21cm am i right :)??

mathhelper · Answer

So close! perimeter = 8√7 + 12√7 + 12√7 , correct up to this point = 32√7 8√7 + 12√7 = 20√7 NOT 20√14 just like 8 apples + 12 apples = 20 apples btw, the triangle is not right-angled.
