To covert degrees Fahrenheit (F) to degrees Celsius (C) we use the equation C<span> = (</span>F<span> - 32) × 5/9</span> . To convert degrees Celsius (C) to degrees <span>Fahrenheit (F) we have to rewrite the equation.
First step: Divide both sides by 5/9. The equation would look like this:
</span>C(9/5) = (F - 32)
Second step: Add 32 on both sides.
32 + (9/5)C = F or F = <span>32 + (9/5)C</span>
Answer:
36x² - 9y²
Step-by-step explanation:
We see that the given expression (6x + 3y)(6x - 3y) looks just like the expression (a + b)(a - b). When multiplied out, this is a difference of squares identity that I highly recommend you memorise:
(a + b)(a - b) = a² - b²
Here, a = 6x and b = 3y, so plug these in:
(6x + 3y)(6x - 3y) = (6x)² - (3y)² = 36x² - 9y²
If one of the numbers you are multiplying by is negative,then that answer will be negative.
11/12 for the first one and 1/3 on the second. I’m 100% sure but I’m sorry if it’s wrong. Have a great day!
