If by 'x' you mean multiplied by, then the answer is yes. anything x 7 = 7 x that same number.
x2+7x-18 = (x+9)(x-2) when factored
x2+7x x(x+7)
X = 10 7x-5=65 +5 +5 7x=70 /7 /7 So X=10
7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)
Do you mean the following? x2 = 4 - 7x If so, then: x2 + 7x = 4 x2 + 7x + 49/4 = 4 + 49/4 (x + 7/2)2 = 65/4 x + 7/2 = ±√65 / 2 x = (-7 ± √65) / 2 So x is equal to (-7 - √65) / 2 and (-7 + √65) / 2
7x + 28
It is an algebraic expression which is equivalent to 7x - 118.
x2+7x-18 = (x+9)(x-2) when factored
The product of 7 and x is 7x, so 5 less than that is 7x - 5
7x-5
7x = 46
35
The expression is: 7x-6
21
You would write that as:4 < 7x
The best algebraic expression for 7 x plus 12 -4 is 7x+8.
It is: 7x
