Answer: B) -6</h3>
Using the box method or FOIL rule, you should find that
An alternative is to use the perfect square formula where in this case a = x and b = 3.
The degrees stay the same.
Multiply the decimal by 60
0.39 x 60 = 23.4
Now take the decimal bit and mulitply by 60 to get the seconds.
0.4 x 60 = 24.
So the answer is: 40 degrees, 23 minutes, 24 seconds.
Equation f(2x+16) multiply each term in the parentheses by f
2fx+16f
Among the statements, this is the true one.
∠BCO is complementary to ∠BOC
ΔBCO is a right triangle. B is 90°.
Interior angles of a triangle = 180°. With B as 90°, the remaining angles, C and O, must total 90°. Thus they are complementary.
