Answer:
75 minutes
1 hour and 40 mins is equal to 100 mins
Divide 100/75 and you get 1.33333, meaning you multiply 75 by 1.33333 to get 100, meaning there is a 33.333333% increase
Step-by-step explanation:
the Answer is 315 because 300 multiplied by 15 so if you add it up you have 315 so your Answer is:315
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
