b2 x 2b = 2b3
What is the answer of (3a+7b) (3a-7b)?
2b + 3 b = 12 . 27 since the beginning is 2 x 12, which equals 24, and then you have to add the extra 3.
-b+5b-2b=2b
This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4
what is 5a x 3 x 2b
4b^2
b2 x 2b = 2b3
3a2b is the simplest formImproved Answer:-3a x 2b = 6ab when simplified
Y = 2bx divide both sides by 2b Y/2b = x
423%2BS=600 Solve that to complete the problem. Let +x+ = her 5th score [ average of scores ] = [ total of scores] / [ number of games ] +120+=+%28+115+%2B+84+%2B+123+%2B+101+%2B+x+%29+%2F+5+ +600+=+115+%2B+84+%2B+123+%2B+101+%2B+x+ +600+=+423+%2B+x+ +x+=+600+-+423+ +x+=+177+ The lowest score Laura will need in the fifth game is 177
( 2ab ) is.
Urmm 4ab ?
2b
(1) x/12=a+9, where a is an integer (2) x/18=b+9, where b is an integer 3x(1) + 2x(2) gives 3x/36 + 2x/36 = 5x/36 = 3a+27+2b+18 = 3a+2b+45 5x/36=3a+2b+45 x=36(3a+2b+45)/5 x=36(3a+2b)/5+9 as 36 is not divisible by 5 then 3a+2b should be divisible by 5 then the smallest solution is a=0 and b=0 and x=9
Assuming the missing sign is "minus" then you have the difference between two squares. This is solved as (x + y)(x - y). In your example x = 4a and y = 2b so the factorisation is (4a + 2b)(4a - 2b) or more completely: (4)(2a + b)(2a - b).
b = 0.2 x 10a = 2aa/(2b) = a/(4a) = 1/4= 25%
