Step-by-step explanation:
A + B = 0
A = -B
(-B)B) = -36
-B^2 = -36
B^2 = 36
B = 6, -6
So, A = -6, 6
A - B = -12
or
A - B = 12
Answer:
It is 5mmxb3m
Step-by-step explanation:
It is what it is
The answer is 120. 6x5 equals one face then multiply that by four because there are four rows. 30x4=120
(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)
=a^2b^2−3ab+3ab−9
=a^2b^2−9
