Option a: is the equivalent expression.
Explanation:
The expression is where
Let us simplify the expression, to determine which expression is equivalent from the four options.
Multiplying the powers, we get,
Cancelling the like terms, we have,
This equation can also be written as,
Multiplying the terms in denominator, we have,
Thus, the expression which is equivalent to is
Hence, Option a is the correct answer.

Answer:
0
Step-by-step explanation:
1) Multiply the first equation by -3: -6x - 3y = 12
2) Substitute 2x + 12 for -3y in the above equation, obtaining:
-6x + 2x + 12 = 12
Then -4x = 0, and x = 0. Letting x = 0 in the first equation, we get:
0 + y = -4, so y = -4.
The x-value at the intersection of the lines is zero (0).
That intersection is at (0, -4).
Answer:
n = 45
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2+2*(4+3)+4+4*n-(200)=0
Step 1 :
Pulling out like terms :
-180 + 4n = 4 • (n - 45)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : n-45 = 0
Add 45 to both sides of the equation :
n = 45
One solution was found :
n = 45
