The rule in /mathemtics, when no brackets are given, is DO THE MULTIPLCATUION/DIVISION before addition /subtraction.
You calculator is programmed this way.
Hence
-3 -2 X 4 = -3 - 8 = -11
Notice I have made the mukltiplication be forde the subtraction.
However, if the sum is wrtitten as (-3-2)x 4 , then you do the brackets first .
( -5) x 4 = -20
It is definitely NOT -6 x 4
You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
8
The 2x4's I use measure 1 and a half by 3 and a half.
There are several simplifications. Each of these is a different way of stating the same value: 8 2x4 4x2 2^3
If a equals 3 and b equals minus 5 then a minus b equals what
2x4 does not equal 7, it equals 8. 2x4=8 is a correct statement.
the answer is 0!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I was the one who made it an unanwser question?
I think you mean this as an answer, not a question. An expression does not have an equals sign (e.g 2x4). An equation does have an equals sign (e.g 2x4=8).
2x4
1x8 2x4 16x.5 32x.25
if you mean 2n=8, then N=4, which translate to 2x4=8
1 1/2 x 3 1/2
2x4-56 2x4=8 8-56= -48)
24 cubic feet
Yes.
because think of 2x4=8 and 8 divided by 4 or 2 equals 4 or2 OK :)
