I kara lines up 3/4 inch buttons, the total length will be
A line plot is given representing the length of the buttons for a craft project, and we have to find the total length of 3/4 inch buttons.
Now, we can clearly see from the given line plot that there 3 buttons having 3/4 inch length.
therefore,
<h3>The total length of 3/4 inch button</h3>
total length =

Answer:
x = 3 and x = 3
Step-by-step explanation:
The given equation is
2x² - 12x + 18 = 0
Divide both sides by 2:
x² - 6x + 9 = 0
We need two numbers that will add up to -6 and their product is 9.
The two numbers are -3 and -3.
=> x² - 3x - 3x + 9 = 0
x(x - 3) - 3(x - 3) = 0
(x - 3)(x - 3) = 0
x = 3 and x = 3
Answer:
- Switch positions of two rows.
- Add elements of one row to another row.
- Multiply elements of one row by a scalar
Step-by-step explanation:
In general, each row represents a linear equation. The rules of equality apply. They allow you to multiply both sides of the equation by a scalar, add equal values to each side of the equation (add one row to another). Rearranging the sequence of equations (swapping rows) does not change the system or its solution.
