You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.

That expression can't be simplified. If you know how much the angle (theta) is, you can calculate the sine (do it on a calculator), and then subtract 1.

It is simply x - 6. The expression cannot be evaluated because the value of x is not given.

0.02 is the equivalent of 2/100 which is the same as 1/50 when simplified

You can't simplify that expression, unless you know specific values for the variables.

I suppose you mean factoring the polynomial. You can check by multiplying the factors - the result should be the original polynomial.

That can't be simplified. If you have a value for x, you can calculate the expression. Be sure to put your calculator into the correct mode; the angle can be measured either in radians or degrees. You have to know what measurement is being used, but if the angle is written as "x", radians are commonly used.That can't be simplified. If you have a value for x, you can calculate the expression.

It is used when multiplying out the brackets of an expression such as (x+3)(x+4) which becomes x^2+4x+3x+12 which when simplified is x^2+7x+12

Just to get you straight, that is actually an expression. Equations have equal signs in them. Just so you know. Anyway, it just so happens that this expression (-6n - 30) is already simplified. There are no like terms to combine there, since 30 does not have an "n".

An algebraic expression does not contain an equality sign. Acting is a form of "expression".

This was my question and I really don't know the answer but all I can say is it can be simplified

No. 151 is a prime number and as it does not evenly divide into 320 we know this can not be simplified.

To "evaluate" an expression, you need to know the value for the variables.

A fraction is in its lowest terms or simplified when the greatest common factor of its numerator and denominator is 1

Is there such a thing as a safe expression of love? He did not know the meaning of that idiomatic expression in Spanish. She wore a puzzled expression as she entered the room.

Idont know factor

When the GCF of the numerator and the denominator is 1.

It cant be further devised.

uh i really don't KNOW ok

My expression of you is very vague, because I don't know you very well.

Be - Know - Do

It is a product if it has a * sign in it.
