Ok. Solve the logarithmic equation. round answer to 3 decimal places, if necessary.

1. log(x+1) + log(x-2) = log4

2. log(base of 5) (x+4) + log(base of 5) x = 1

I know the addition means multiplication, right? well I can't seem to factor it out right. But this is going to be graded and I really need to get a 100! So please help me, or atleast help me solve the equation to get the answer!

The first one my answer is 141.42, i really think i am major wrong with that one lol

And for the second one i got - 4

Thanks!

epicatechin is an antioxidant found in cocoa and cacoa type products. ORAC is the most reliable system for measuring antioxidant activity in food products and is measure as microM/g (more commonly known as Trolox Equivalents (TE)/g). i have found a chocolate to use in a food product that has the antioxidant content as epicatechin units (mg)

"Eternally blue skies, palm trees, a bone dry climate, red earth, mountains around the big city, with a slightly extraterrestrial, "Mars Oasis" feeling; abundant lifestyle comforts like swimming pools, theme restaurants, and golf courts everywhere."

Where could that be? What do you think? It sounds like just the place I'd want to live in.

1) If the metric system is adopted for everyday use fabric will be sold in meters (not yards), milk in liters (not quarts), and meat in kilograms (not pounds). Given that 1 inch = 2.54 cm, 1 pint = 473.2 ml, and 1 pound = 453.6 g, what percentage increase does each of the following represent?
a) fabric: 1.00 meter instead of 1 yard,
b) milk: 1.00 liter instead of 1.00 quart,
c) meat: 1.00 kilogram instead of 2.00 pounds.

2) One cord of wood (a stack 4 ft high by 8 ft long by 4 ft deep) has a volume of 128 ft^3. What is the volume of 1 cord in m^3? One inch equals 2.54 cm exactly.

All off the following are movements plants can accomplish except:

1 folding and unfolding of leaves
2 rapid responses using action potentials
3 growth movements up or down in response to gravity
4 growth movements toward or away from light
5 changes in plant growth in response to touch

I think it is 4 because of phototropism, am I correct
(doubts in 3 and 4)

Thank You
