b2 - 7b - 6
b = -4
(-4)2 - 7(-4) - 6 = 16 +28 - 6 = 38
2*3*4 = 24
Unfortunately there is no expression to evaluate!
Evaluate the expression below when x = 2.3x2-2x+4
If x is 4 then 34.5x evaluates to 34.5 times 4 = 138
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15
2*3*4 = 24
There is no box below!

You take the expression and, wherever there is the variable n in the expression, you substitute 12. Wherever there is m, you substitute 4. Then you evelaute the expression.For example n2 - 2mn + 27m = 122 - 2*4*12 + 27*4 = 144 - 96 + 108 = 156
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
Simple! The value of 4 is four. It equals 4.
[10-(4*2)]*3
To evaluate the expression -3 + 7 - (-4), you first simplify the double negative. This becomes -3 + 7 + 4. Now, calculate: -3 + 7 equals 4, and adding 4 gives you a final result of 8. Thus, -3 + 7 - (-4) equals 8.
12 - 10 + 4 = 6
16 lol?
Evaluate the following expression to 4*(12.25-4)/(9+2)
-2-3=+7
