Answer:c
Step-by-step explanation:
good luck
Sometimes there is no apparent way to factor it by hand /(the factors are decimals or imaginary). To try and factor these problems is nearly impossible in your head.
Answer:
x ≥ 1/2
x ≤ -3
Step-by-step explanation:
2x² + 5x - 3 ≥ 0
Factor left side.
(2x - 1)(x + 3) ≥ 0
Set factors in an inequality to 0.
2x - 1 ≥ 0
2x ≥ 1
x ≥ 1/2
You multiply both sides by 2x - 1, so the sign switches.
x + 3 ≤ 0
x ≤ -3
Answer:
1.5 amps
Step-by-step explanation:
P = V.I
60 = 40.I
60/40 = 40.I/40
I = 1.5
Go by each term and simplify
a(a^2)-a(ab) + a(b^2) + b(a^2) - b(ab) + b(b^2)
you get
a^3-a^2b +ab^2+a^2b-ab^2+b^3
simplify more
a^3+b^3
I'm not sure but tell me if i'm right
