Answer:
This means c=100. The factored form is .
Step-by-step explanation:
A perfect square is a trinomial that factors into the form . To find the value of C to finish the perfect square divide 20 by 2 and square it.
20/2 = 10
10*10=100
This means c=100. The factored form is .
Answer:
7 inches
Step-by-step explanation:
Using Pythagoras' theorem on the right triangle, that is
r² + 11² = 13²
r² + 121 = 169 ( subtract 121 from both sides )
r² = 48 ( take the square root of both sides )
r = ≈ 7 in ( to the nearest inch )
