Answer:
x = 3/2
Step-by-step explanation:
(2x + 3)2 – 4(2x + 3) - 12 = 0
Simplify the equation then isolate for x.
Distribute over brackets:
(4x + 6) – (8x + 12) - 12 = 0
Combine like terms:
4x + 6 – 8x + 12 - 12 = 0
6 - 4x = 0
Isolate x:
6 = 4x
6/4 = x
Reduce the fraction:
6/4 = x <= divide top and bottom by "scale factor" of 2
3/2 = x
x = 3/2 <= having x on the left side is standard
Neither, turn 80% into a decimal, 0.8, then multiply.
8000 is 1000 times larger than 8
Answer:
The first one is 14.5 and the second one is that the decimal moves to the left every time a zero is added to the first number
Step-by-step explanation:
The first one 5 lb is the answer
