<h2>Steps</h2>
So to find the solutions, I will be factoring by grouping. Firstly, what two terms have a product of 12x² and a sum of -8x? That would be -2x and -6x. Replace -8x with -2x - 6x:
Next, factor 4x² - 2x and -6x + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:
Now you can rewrite it as:
Now, apply the zero product property and solve:
<h2>Answer</h2>
<u>In short, x = 3/2 (1.5) and 1/2 (0.5).</u>
The answer would be 400 seconds
Answer:
70 degrees
Step-by-step explanation:
Moving from one hour number to the next (12 to 1, 3 to 4, etc) moves the hand of the clock 30 degrees. Using this, we know that the hour hand moved 60 degrees to get to the hour number 2. Then, the angle the hour hand moved because of the minute hand can be calculated by doing (20/60)*30=10. So the final answer would be 70 degrees.
You would use a 5 by 6 tile because you would find a common factor of 24 and 20 which is 4.
24 divided by 4 is 6
20 divided by 4 is 5
So the tiles used to cover the stone would be 6 by 5 tiles
Hope this helps :)
