Answer:
{ 0, 3, - 3 }
Step-by-step explanation:
f(x) = x(2x - 3)(x + 3)
to find the zeros let f(x) = 0 , that is
x(2x - 3)(x + 3) = 0
equate each factor to zero and solve for x
x = 0
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 
x + 3 = 0 ⇒ x = - 3
zeros are { 0,
, - 3 }
Answer:
Step-by-step explanation:
Complementary angles form a right angle and supplementary angles form a straight angle.
<h3>#7</h3>
<u>Complementary:</u>
<h3>#8</h3>
<u>Supplementary:</u>
- 2x + 6x + 20 = 180
- 8x = 160
- x = 20
Answer:
C. 55°
Step-by-step explanation:
Note the total measurement of angles for a triangle. The total measurement of all angles in a triangle = 180°
Note that m∠C is a right angle (as shown through the square), and that right angles = 90°
Subtract to find the measurement of the unknown angle (∠B)
∠B = 180 - (∠A + ∠C)
∠B = 180 - (35 + 90)
Simplify. Combine like terms. First, add (solve parenthesis), then subtract.
∠B = 180 - (125)
∠B = 55
m∠B = C. 55°
