The following steps of solving for the roots of 2x² - 4x -3 = 0 were retrieved from another source
Step 1 2x² - 4x = 3
Step 2 2(x² - 2x) = 3
Step 3 2(x² - 2x + 1) = 3 + 1
Step 4 2(x - 1)² = 4
From this, we can see that on Step 3, Tran made a mistake of adding 1 to 3. As we can see, 2(x² - 2x + 1) = 2x² - 4x + 2. That means, instead of adding 1, it should have been 2.
Therefore, the step that Tran first made an error is Step 3<span>.</span>
Answer:
option D
Step-by-step explanation:
Let the price be p
7% of price = 0.07p
Price after decrease = p - 0.07p
Answer:
ok, what's the question?
Step-by-step explanation:
<span>To solve the problem, to 40%
of the total customer should be solve. And this can be solve by muliplting it
by the fraction (0.4). so 140 x 0.4 = 56 customers. Since Trudy has already 60
of her sutomers job ready then she met her target.</span>
V=29,564-532t would be the equation for that scenario
