The important thing to note is that multiplication is just repeated addition. Thus nine x can be written as x+x+x+x+x+x+x+x+x. And we want to add another x onto the end of that. This can then be simplified back to the multiplication 10x. Therefore an equivalent expression to 9x+x is 10x
what is equivalent to (x plus 4)2
7x + 28
when you say 3x, you mean that there are 3 x's. Multiplication implies repeated addition, so three x's added is x+x+x, which equals 3x.
x2 - 9x + 20 = (x - 4)( x - 5)
which expression is equivalent to (3 x 10^3) (5 x 10 ^5) sorry that is what i ment
It is an expression.
what is equivalent to (x plus 4)2
Yes, -6+x is the same as x-6.
7x + 28
'X-7 plus 23-6' can be simplified and expressed as: 'x+10'
It is: 5x+31
when you say 3x, you mean that there are 3 x's. Multiplication implies repeated addition, so three x's added is x+x+x, which equals 3x.
To find an equivalent expression to ( 4 + 3(5 + x) ), first apply the distributive property: ( 3(5 + x) = 15 + 3x ). Then, add this result to 4: ( 4 + 15 + 3x = 19 + 3x ). Thus, an equivalent expression is ( 19 + 3x ).
x2 - 9x + 20 = (x - 4)( x - 5)
It is: 4(6x+x) = 24x+4x => 28x
3x2y - 4xy + 4x
It is a quadratic expression in x, which is equivalent to 3*(x+1)*(x+5). Since it is not an equation it cannot be solved.
