How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
What is equevitent to 7s plus 2s?
The equivalent of 7s plus 2s is 9s.
What is the answer to 2s-12 plus 2s equals 4s-12?
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
What is the answer to 2s plus 16 equals 4s - 6?
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
How many U-2 planes have crashed?
In the current issue of Air & Space (May 2012) it states that"five U-2s were shot down with Russian=developedSA-2 surface-to-air missiles . . ." This is a in an article where a Chinese pilot is interviewed and the context is U-2s shot down by the Chinese. The statement is made, however, by the interviewer as partof a question and not by the Chinese pilot, so I assume it is accurate. I also assume that this is in addition to Gary Powers being shot down over Russia. Reading this was the first I had heard of other U-2s being shot down.
How do you determine the equation for the perpendicular bisector of the straight line joining the points s 2s and 3s 8s?
A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s
What is 9r squared-4s square over 9r plus 6s?
9r2-4s2/9r+6sIt looks like you can factors the numerator(3r + 2s)(3r - 2s) [This is the factored form of 9r2-4s2]Put this back into the equation(3r+2s)(3r-2s)/9r+6sYou can also factor the denominator3(3r+2s)Put this back into the equation(3r+2s)(3r-2s)/3(3r+2s)You can cancel out the 3r+2s on top and bottom because they are the same they equal 1. Therefore your final answer is3r-2s over 3You could go further and say this is...r-(2/3)seither one is correct
What is the name of compound (NH4)2S?
The compound (NH4)2S is ammonium sulfide.
What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
What is the answer to 5s - 6 equals 2s?
5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
How many 2's are there between 200-300?
100 2s for the hundreds digit of 200-30010 2s for the tens digit of 220-23010 2s for the ones digit of 200-300________________________________120 '2s'
What is 2s plus 17 equals 2s plus 17?
2s + 17 = 2s + 17 1) First, you want to start on the left side of the equation and subtract 17 from both sides. 2s = 2s 2) Then, you take the 2 on the left side and divide it on both sides. s = s 3) You are left with s (Or 1s) on both sides, so s = 1.
