Answer:
D) 4
Step-by-step explanation:

Answer:
C
Step-by-step explanation:
9x² - 4
can be factored as a difference of squares , that is
(U + V)(U - V)
9x² - 4
= (3x)² - (2y³)²
with U = 2x and V = 2y³
First, isolate the decimal. second, put it over the correct denominator based on the decimal place: 96/100. Next, divide by a number that goes into both 96 and 100. 4 works.... 24/25. And that is your answer, after you add the original 2 back: 2
A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36
B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B
distance between 2 points x and y is |x-y|
so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68
7.
If c = 16
that means the equation is
16 - 9
which is 7
so 7
