A cubed
(x-8)(x+8)
3(x^2 +7) is the same as 3x^2 + 21 to find the answer of x set an value to the equation
Write an algebraic expression for the verbal expression. q squared minus 2 times q
The answer could be (11 - x)*(11 + x).But it could also be 122 - x^2 - 1.
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
It is: The product of 122 is 144
(x-8)(x+8)
distributive
pi times 1/3 times the radius squared times the height
x = 3/sqrt(2) or 1.5*sqrt(2)
The expression is 15*11
there could be many... sin2(a/2) / cos2(a/2)
3(x^2 +7) is the same as 3x^2 + 21 to find the answer of x set an value to the equation
You can only get a specific number for an expression if you assign numbers to the variables. As an expression, the existing expression cannot be simplified.
Write an algebraic expression for the verbal expression. q squared minus 2 times q
It is an expression whose value will depend on the value of the variable x.
The algebraic expression for x times x is x2 ( x squared).
