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
Answer:
0.195
Step-by-step explanation:
So you're trying to figure out the number of miles in a day, so you could do:
<u>total miles</u> = <u>miles</u>
total time day
<u>932.4 miles</u> = 310.8 miles per day
3 days
The number for 5.71 ×10^-3 is .00571
The expressions which demonstrates the identity property of multiplication is; 25(1) = 25 option B
<h3>Identity Property</h3>
Identity Property of Multiplication states that any number multiplied by 1 does not change, that is, it is constant or remains the same
Check all options
25(0) = 25
0 = 25
Not true
25(1) = 25
25 = 25
True (identity property of multiplication holds)
25 + 0 = 25
25 = 25
True (Not identity property of multiplication)
25 + 1 = 25
26 = 25
Not true
