D 12
multiply six times two answer is 12
Answer:
Yes.
Step-by-step explanation:
You can find it out by factoring but ill do it easier way.
(x + 1 ) = 0 put the first and second equation to 0
x = -1
x³ + 2x² - 5x - 6 = 0 Now plug in the x in the equation
(-1)³ + 2(-1)² - 5(-1) - 6 = 0
0 = 0
so (x + 1) is a factor.
Just add up the 3 legs of the triangle representing J's walk.
From (2,9) to (7,9) is 5 miles; from (7,9) to (2,2) is sqrt(25+49) miles (using the Pythagorean Theorem); and from (2,2) to (2,9) is 7 miles.
Add these 3 lengths together to obtain your final answer.
Sin0 actually will equal cos(pi)/2. this is because sin0 is equal to 0, but cos0 is equal to 1. therefore, that cannot be correct.
