Hello! And thank you for your question!
First add 7 to both sides:
x/5 = 4 + 7
Then simplify 4 + 7:
x/5 = 11
After that, multiply both sides by 5
11 x 5 = x
Finally, Simplify 11 * 5:
x = 55
Final Answer:
x = 55
To find the reciprocal, you just flip the fraction upside down, so it would be D
Given: Different equations
To Determine: Which would be best solved using difference of two squares
Solution
The factorization of a difference of two squares is given below
Let us examine each of the given equation
From the above,
The two equation above can be solved by difference of two square, but the equation below is the easiest solved using differnce of two square
x² - 25 = 0
Answer:
D) {-1}
Step-by-step explanation:
A rational expression is "not defined" when its denominator is zero. Hence to find values of x that make the expression "not defined," you solve the equation ...
denominator = 0
2x +2 = 0 . . . . . . put the actual denominator into the equation
x + 1 = 0 . . . . . divide by 2
x = -1 . . . . . . . . subtract 1
The expression is "not defined" for x in the set {-1}.
