Answer:
B) 1 < x < 13
Step-by-step explanation:
use triangle inequality theorem which states that the sum of any two sides must be greater than the third side
let x = third side
6 + 7 > x; x < 13
6 + x > 7; x > 1
x + 7 > 6; x > -1
there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative

Answer:
b.
Step-by-step explanation:
Factor 25p^ 2 -81q^ 2 : (5p + 9q)(5p - 9q)
Steps
25p ^ 2 - 81q ^ 2
=(5p)^ 2 -(9q)^ 2
Apply Difference of Two Squares Formula: x ^ 2 - y ^ 2 = (x + y)(x - y)
(5p) ^ 2 - (9q) ^ 2 = (5p + 9q)(5p - 9q)
=(5p+9q)(5p-9q)
