D because n= -14 and were dividing 56
Its
C. Draw a line connecting the the intersection of the arcs below and above the segment.
The answer is A for this problem
It is equal because every 2000 pounds is 1 ton and 18000lb divided by 2000 equals 9.
a^2 - b^2 = (a + b)(a - b)
In this case
49x^4y^2 - 4z^2
= (7x^2y)^2 - (2z)^2
= (7x^2y + 2z)(7x^2y - 2z)
Factors are (7x^2y + 2z) and (7x^2y - 2z)
Answer:
D) 7x^2y + 2z
