Answer:
9,849
Step-by-step explanation:
AC = -1 - ( -5) = 4
BC = 4 - ( -5) = 9
AM^2 = AC^2 + BC^2
AM^2 = 4^2 + 9^2
AM^2 = 97
AM = sqrt(97)
AM = 9,849
Done

Answer:
the answer is...
Step-by-step explanation:
Answer:
X=9 or x=-9
Step-by-step explanation:
X^2=81
Can be written as
x^2-81=0
Factorize by the property:
a^2-b^2=(a-b)(a+b)
So the expression becomes:
(x-9)(x+9)=0
Therefore, either x-9=0or x+9=0
Then the solutions are x=9 or x=-9
