Answer:
Step-by-step explanation:
f(x) = (x + 2)(x +6)
1) The function is positive for all real values of x where x > –4 :
COUNTER-EXAMPLE : x = - 3 you have -3>-4 but (-3+2)(-3+6) = -1 ×3 =-3 no positive .
2) The function is positive for all real values of x where
x < –6 or x > –3.
COUNTER-EXAMPLE : x = - 2.5 you have -2.5>-3 but (-2.5+2)(-2.5+6) = -0.5 ×3.5 =-1.75 no positive .
same method for the statement : "The function is negative for all real values of x where
x < –2."
conclusion : statement about the function is true: "The function is negative for all real values of x where
–6 < x < –2."
.
We have an equation: 2*? = 76
⇒ ?= 76/2
⇒ ?= 38
The final answer is 38~
Answer:
First you would multaply 4 and 5 because you can multiply before you get the square because the is inside the peranthies.
Answer:
<h2>9s</h2>
Step-by-step explanation:
63s² = 9 · 7 · s · s = (9s)(7s)
Therefore GCF(9s, 63s²) = 9s
