Answer:
Answer:
Step-by-step explanation:
1st expression:4a(a-b)
2nd expression:9a(a-b)
So L.C.M=a(a-b)4×9
=36a^2-36ab
Step-by-step explanation:
m∠abc = m∠ebf = 58°
reason: vertical angles
m∠cbf = 180-m∠ebf = 180-58 = 122°
reason: Supplementary angles
m∠dbe = 90-m∠ebf = 90-58 = 32°
reason: complementary angles
Answer:
-3·m^12·n^6
Step-by-step explanation:
We assume you intend ...
(-24·m^5·n^4)/(8·m^-7·n^-2)
= (-24/8)·m^(5-(-7))·n^(4-(-2))
= -3·m^12·n^6
_____
If you really intend what you have written, then it simplifies to ...
(-24·m^5·n^4/8)·m^-7·n^-2 . . . . . note that all factors involving m and n are in the numerator
= (-24/8)·m^(5-7)·n^(4-2) = -3n^2/m^2
Answer:
<u>18</u>
Step-by-step explanation:
You basically have to do 13.5 divided by 0.75 (3/4) which equals 18
