Question

Find the perimeter of the figure below. Show all work for each step. Work should include explanations in words detailing how you simplify each specific radical. Take your time and be thorough. Include units in final answer. Use radicals in your work and not decimals!

Answer 1

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

Answer 2

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 :)??

Answer 3

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.
