Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
U should multiply a on both sides then you would get au=k/b divide by u and get a=k/ub
Answer: Substitution Property
Think of "substitute" as in replacement. For example, your substitute teacher is a (<span>temporary) </span>replacement for your current teacher. In this case, we're replacing "m4" with "20 degrees".
Step-by-step explanation:
The given GP is : -0.5+1.5-4.5........
It is required to find the sum of 45 terms of GP.
From this GP, first term is (-0.5).
Common ratio is,
The formula use to find the sum of n terms of a GP is given by :
Substituting all values in above formula :
Hence, this is the required solution.
