It is: (-10)+(-3)+4 = -9

If x = 3, then x + 10 would be 3 + 10, which is 13.

3 + √x = 10 √ x = 10 - 3 √ x = 7 x = 7² x = 49

X + 3 = 10. X + 3 - 3 = 10 - 3 X = 7 Double check your solution. X + 3 = 10 7 + 3 = 10 10 = 10 So X + 3 = 10 when X = 7.

x^2 + 13x + 30 = 0 x^2 + 10x + 3x + 30 = 0 x(x + 10) + 3(x + 10) = 0 (x + 3)(x + 10) = 0 x = -3 or x = -10

Add the following: 10 x 10 plus 2 x 10 plus 3 x 10 plus 2 x 3 That makes it easier to do it without a pen or calculator.

3+10 = 13

If (x+7) > 10, then x > 3. If (x+7) < 10, then x < 3.

337,060 = (3 x 10^6) + (3 x 10^5) + (7 x 10^4) + (0 x 10^3) + (0 x 10^2) + (6 x 10^1) + (0 x 10^0)

if it is -X then X=5 if it was minus X the X=10
