Did you learn how to factor the difference of two squares ?
This thing is the difference of two squares.
The first term is the square of 5x .
The second term is the square of 4 .
When it's factored, it's
(sum of the square roots) x (difference of the square roots) .
25 x² - 16 = (5x + 4) times (5x - 4) .
To check it, go ahead and FOIL that out, and you'll get 25x²-16 .
That is the pattern 34,000,000
Answer:He bought 9 cans.
Step-by-step explanation:
27divided by 3 is 9.
Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
Answer:
slope is change in rise(y) over change in run (x), change in y here is 36 and change in x is 2, slope is 36/2=18
