Answer:
x = -3, 2, 3.
Step-by-step explanation:
f(x )= x^3 - 2x^2 - 9x + 18 We factor this by grouping:
f(x) = x^2(x - 2) - 9(x - 2)
f(x) = (x ^2- 9)(x - 2)
f(x) = (x - 3)(x + 3)(x - 2).
The zeroes of the function are:
x = -3, 2, 3.
Answer:
14. 58 degrees
16. 11 degrees
Step-by-step explanation:
14. The sum of all 3 interior angles of a triangle is 180. We know right angles are 90 degrees. So 180 - 90 - 32 = 58 degrees
16. When two parallel lines are cut by a transversal, the corresponding angles have the same measure. So the angle above angle a has the same measure as the 169 degree angle in the same position on the other line. I hope those words make sense. Then angle a and the angle above it (which we know = 169 degrees) combine to make a straight line/straight angle, which = 180 degrees. 180- 169 = 11

Hi, I think what you need to do is multiply 21 x 4 x 1/3. If you need help multiplying there’s a helpful website called Calculator Soup that is very helpful.
