Answer:
(s*t)(-7) = 987
Step-by-step explanation:
s(x) = 2 - x²
t(x) = 3x
To find (s*t)(x), multiply s(x) and t(x).
(s*t)(x) = (2 - x²)(3x)
(s*t)(x) = 6x - 3x³
Now that you have (s*t)(x), plug -7 in.
(s*t)(-7) = 6(-7) - 3(-7)³
(s*t)(-7) = 6(-7) - 3(-343)
(s*t)(-7) = -42 + 1029
(s*t)(-7) = 987
Of course Lebron is black, lol.
Answer:
15.38%
Step-by-step explanation:
there are four 10 cards and four jack cards.
