22/2 - 2
s=4
Yes
if s is 2, 2s is 4. 3 squared is 9. 4 + 9 = 13. 13 / 5 = 2.6, which is not equal to 2.
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)
(2*2*2)+2/2=9
9(2s-7)
It is a simple linear equation in 's'. Its solution is the number that 's' must bein order to make it a true statement. The solution may be found like this:4s + 10 = 2s + 2Subtract 10 from each side of the equation:4s = 2s - 8Subtract 2s from each side:2s = -8Divide each side by 2 :s = -4
If you mean: 4(2s-1) = 7s+12 then the value of s works out as 16
36
You can use three 2s to make 26 as follows (2x2)! + 2 = 26 So you can simply make 26 with five 2s as (2x2!) + 2 - 2 + 2 = 26
Assuming 34 is 3/4:Jane is 12To solve:S+4 = 3/4(J+4)(J-4) = 2(S-4)S = 3/4(J+4)-4J = 2S-4S=3/4(2S-4+4)-4S=3/4(2S)-4S=8J=2(8)-4=12
