Answer:
x = - 2, x = - 3, x =
Step-by-step explanation:
to find the zeros equate p(x) to zero , then
(x + 2)(2x² + 3x - 9) = 0 ← factor the quadratic
(x + 2)(x + 3)(2x - 3) = 0
equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 3 = 0 ⇒ x = - 3
2x - 3 = 0 ⇒ 2x = 3 ⇒ x =
Answer:
The missing value is 6
Step-by-step explanation:
We know that there are 5 values but only 4 are given:
⇒ The given values are: 8, 14, 7, and 13
⇒ Let the fifth value be "x"
We also know the mean which is 9.6
<em><u>Solve for the missing value:</u></em>
⇒ 9.6 (mean) =
<em>multiply 5 on both sides </em>
⇒ 9.6 x 5 = x 5
⇒ 48 = 8 + 14 + 7 + 13 + x
<em>add the numbers:</em>
⇒ 8 + 14 + 7 + 13 + x = 42 + x
<em>the equation becomes: </em>
⇒ 48 = 42 + x
<em>Now, subtract 42 on both sides:</em>
⇒ 48 - 42 = 42 - 42 + x
⇒ 6 = x
