First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
there is no way to simplify 47
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
Without an equality sign and not knowing the plus or minus values of 7x and 4 the given expression can't be considered to be an equation
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
5/(8 + √7) = (40 - 5√7)/57 is the rationalised equivalent.
-1?
It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
4√3 + 7√3 = (4 + 7)(√3) = 11√3
It is 8 + (7/8)*y
4 radical 6
The expression cannot be simplified.
It's an expression that can't be simplified.
What do you mean "simplified"? It can definitely be factored.
If that is l and not 1 then it is 3.5l+2s when simplified
The given expression cannot be simplified.
The expression is: 6-5x when simplified
