The answer is <span>49x2 _ 84x + 36
</span>
(7x - 6)² is the square of the difference. The general formula would be:
(a - b)² = a² - 2ab + b²
In our expression (7x - 6)², a would be 7x and b would be 6:
(7x - 6)² = (7x)² - 2 · 7x · 6 + 6²
= 7² · x² - 84x + 36
= 49x² - 84x + 36
A boat moves at a rate of 40 mph in Stillwater if the rivers current flow in a rate of 4 mph how long does it take a boat to travel 22 miles upstream?
upstream rate: 40 mph - 4 mph = 36 mph
how long: 22 miles/36 mph = 0.6 h = 36 minutes
I think you meant "evaluate the given equation."
<span>3x – y = 1 becomes 3x-1=y. Then: 3(-1)-1 = y = -4 when x=-1.
The y-values for {0, 1, 3} are {-1, 2, 8}</span>
