Answer:
Well factorizing 16x^2-49
You can use the difference of squares
Which is when theirs 2 perfect sqaures and it’s a subtraction problem.
So 16x^2 - 49
the formula is
a^2-b^2= (a+b) (a-b)
16x^2 - 7^2 = (a+b) (a-b)
SO plug it in
(4x+7) (4x-7)
Thats simplified to the max
So your answer would be (c)
16x² - 49
= (4x)² - 7²
Identity =》 a² - b² = (a + b) (a - b)
(4x)² - 7²
= (4x + 7) (4x - 7) [3rd option]

Answer:
5 units. Since they have the same y coordinate the x coordinate determines the distance from each other. In the case 9-4=5.
