No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
9x2 + 24xy + 16y2 = 9x2 + 12xy + 12xy + 16y2 = 3x(3x + 4y) + 4y(3x + 4y) = (3x + 4y)*(3x + 4y) = (3x + 4y)2
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
It is equivalent to 15x+10
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
9x2 + 24xy + 16y2 = 9x2 + 12xy + 12xy + 16y2 = 3x(3x + 4y) + 4y(3x + 4y) = (3x + 4y)*(3x + 4y) = (3x + 4y)2
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
It is equivalent to: 3x+6+5 = 3x+11
It depends on what it is meant to be equivalent to!
4. 12x^2-64x-256=4(3x^2-16x-64)
It is equivalent to: 3x+6+5 = 3x+11
3x^2
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
It is 22/10*(3x + 2)
