The question is on number of subsets
Number of subset is given by 2^n
n=3 in our question, A,B,C
2^n = 2^3 =8
They are; { }, A, B, C, AB, AC, BC, ABC
Answer: m² + 3m - 10 = 0
Step-by-step explanation:
From the expression, considering
6x + 5 = m
The original expression
( 6x + 5 )² - 10 = -18 - 15
Factorize the right hand expression,
-18 - 15 = -3( 6x - 15 )
Since m = 6x + 5 , we now substitute for m in that expression
m² - 10 = -3m
Now re arrange the equation in the form,
ax² - bx + c = 0
Now back to the equation,
m² + 3m - 10 = 0,
So the equivalent equation will be
m² + 3m - 10 = 0
Answer:
n = 5.2.
Step-by-step explanation:
-20.8 = -4n
We divide both sides of the equation by -4:
-20.8 / -4 = -4n/-4
5.2 = n (answer).
