Answer:
49x²-16 = (7x - 4)(7x + 4)
Step-by-step explanation:
Your "49×2-16" is incorrect; did you mean "49x^2-16" or "49x²-16?"
This last expression is the difference of two squares.
The formula for that is a² - b² = (a - b)(a + b), and so your 49x²-16 factors as follows:
49x²-16 = (7x - 4)(7x + 4)
8xy+65 take the 8 and multiply it to the 8 on the inside and that would be 64. 64 plus 1 is 65
Answer:
No, she doesn't have enough varnish for all the floors.
Step-by-step explanation:
Area of the floor, A= 10x6-5x2=50
Since 5 m^2 required 1 liter of varnish.
So, the amount of varnish required for 1 = 1/5= 0.2 liters.
The amount of varnish required for 50 = 0.2X50=10 liters.
Now, as 1 tin has 2.5 liters of varnish.
So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.
Hence, she doesn't have enough varnish for all the floors.
