What is 4x plus 1 equals 2x plus 12 equals?
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
How do you factor 2x2x plus 5x plus 2?
(2x + 1)(x + 2)
What is 2x squared minus 2x?
Factored?2X2 - 2X2X(X - 1)================If this were set to 0, X = 0 and X = 1
How many cubic feet in 2x2x 3m?
2m x 2m x 3m is equal to 12 m3 (cubic metres)12 m3 is equal to 423.776 ft3 (cubic feet)
The reciprocal of 5 less than a number is 4 times the reciprocal of twice the number?
1/(x-5) = 4/(2x)4(x-5) = 2x4x - 20 = 2x2x = 20x = 10_______________________________Check:1/(10-5) ?=? 4/(2x10)1/5 ?=? 4/201/5 = 1/5 yay!
What property can you use to combine two like terms to get a single term?
You don't use a 'property" to combine like terms, you use an "operation". To combine like terms, use the following operations:Addition: 4x+3x=7xSubtraction: 4x-3x=1x=xMultiplication/Division:4x = 2x + y-2x + 4x = 2x + y -2x2x = y1/2 * 2x = y * 1/2x = y/2check: x,y=(10,20)4*10 = 2*10+2040 = 20+2040 = 40 = true==============You are absolutely right! I stand corrected: But if the asker wants to know, it is the distributive property of like terms which makes combing them possible as illustrated in the examples, above. Thanks.-----You can use the distributive property to combine like terms.For example, take 3x+5x. By using the distributive property, this is the same as x(3+5). Since 3+5=8, the sum of 3x and 5x is 8x.
How much does it cost to plant one tree?
Costs vary as to the type of trees and the area to be worked. As regards fir trees, the figure of $65 per acre has been circulating. Energy costs are pushing that figure higher. The "missig link" in this activity is the time it will take for the trees to grow up and "reforest" the forest. Seedlings are started and planted by the millions every year, but the old growth forests they replace when grown up support a slightly different group of critters. One classic example might be the marbled murrelet, which only nests in old growth forest, like Pacific Coast redwoods. And how long does it take for a redwood to mature? Maybe five hundred years? Maybe a thousand? Wikipedia has an article, but at this writing it is a stub. It does, however, have links to related material. Why not surf on over and check it out. Oh, need a link? You got it.
