Option B: (b-a)/(b+a) is the correct answer
Step-by-step explanation:
The given expression is;
First of all we have to take LCM in both numerator and denominator
So,
The reciprocal of the denominator will be multiplied with the numerator for simplification
So,
Hence,
Option B: (b-a)/(b+a) is the correct answer

Answer:
- 3x³-6x²
- 3x²+x-2
- -16
Step-by-step explanation:
For 1: Multiply both functions together, expand, then simplify
(x-2)(3x²) = 3x³-6x²
For 2: Just add both functions together
For 3: Subtract both functions to get -3x²+x-2 and substitute x with -2
-3(-2)²-2-2 = -16
X = 5 and 2x = 10
the only solution is 5, can be any number
Answer:
C. AC/BC = DF/EF
Step-by-step explanation:
Hi en that ∆ABC ~ ∆DEF, the corresponding sides of ∆ABC and ∆DEF would be proportional to each other.
AB corresponds to DE
AC corresponds to DF
BC corresponds to EF
Therefore,
hypotenuse over one of the leg of ∆ABC = hypotenuse over one of the corresponding legs of ∆DEF, which is:
AC/BC = DF/EF
