The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below:Step 1: 3(2x − 4) = 8 + 2x + 6 Step 2: 5x − 7 = 14 + 2x Step 3: 5x − 2x = 14 + 7 Step 4: 3x = 21 Step 5: x = 7 In which step did the student first make an error and what is the correct step? Step 2; 6x − 12 = 14 + 2x Step 2; 6x − 7 = 2(6 + x + 4) Step 3; 5x − 2x = 14 − 7 Step 3; 5x + 2x = 14 + 7

x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.

Step-by-step explanation:
Slope of a line passing through two points and
will be given by,
Slope 'm' =
Function 'f' passes through two points (0, 20) and (1, 35).
Slope of the line =
= 15
Similarly function 'g' is passing through (0, 22) and (1, 37).
Slope of the line = 15
Therefore,
Since, slopes of both the lines are equal, lines will be parallel.

232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36
Answers
Here, we can let 23 = a and 17 = b, so using this method, we have
23² - 17² = (23+17)(23-17) = 40 × 6 = 240
So third option is correct.
Answer:
Your answer is 23^2 − 17^2 = (23 + 17)(23 − 17) = (40)(6) = 240, or C on your answer sheet.
Step-by-step explanation:
Lets begin!
So when a binomial is composed of two perfect squares separated by a subtraction symbol, a certain method called the difference of perfect squares can be used. The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots.
So, to solve:
23^2 - 17^2 = (23 + 17)(23-17) = (40)(6) = 240
Thus being your answer.
