8x to the second power times 3x to the second power
(8x)2 + (3x)2 = 64x2 + 9x2 = 73x2
is one possibility, except the problem called for multiplication which would make the answer 64x squared times 9x squared = 576x to the fourth power
It could also be read this way: 8x squared times 3x squared equals 24x to the fourth power. I wish my computer would do those cool little twos.
8x to the second power is 64x2
3x2 - 8x = x(3x - 8)
5 - 8x + 3x2 = 3x2 - 8x + 5 (since the sign of the second term is negative, then 5 can be factored as (-1)(-5)) = (3x - )(x - ) (try to put 1 or 5 to the empty places, in order to obtain -8x) = (3x - 5)(x - 1)
It depends on what it is meant to be equivalent to!
3x + 2x - 8x + 2x = -x
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
5x+8x+3x-2x = 14x
8x(1 - 3x)
10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3
8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5
It is: 30x+80 -8x = 22x+80 when simplified
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
Multiply the first by 8 and the second by 3
3x + 6x - x= 8x
Width = X Length = 3X Four sides to the perimeter: x + x + 3x + 3x = 8x 8x = 22 x = 2.75 3x = 8.25 The length is 8.25.
It is equivalent to: 3x+6+5 = 3x+11
-3x + 1
If you mean: -3x-5x+1+8x-2x-9 then the result is -2x-8
