Answer:
Step-by-step explanation:
(3b)³ = 3³·b³ = 27b³
Answer:
f(- 2) = - 1
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 3 - (- 2)² = 3 - 4 = - 1
D = 171 - (61+53) = 171 -124 = 47
E = 171 - 90 = 81
A = 81 - (34+24) = 81 - 58 = 23
B = 61 - 23 = 38
C = 90 - (33+ 38) = 90 - 71 = 19
answer is B.
The answer will be the last one as it equals 4x + 3. this means that the equation will be parallel and does not have a solution.
