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
10 + 3(x + 2) = 31
7
It is: (-10)+(-3)+4 = -9
If x = 3, then x + 10 would be 3 + 10, which is 13.
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
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
1 plus 1 x 2 plus 3 x 42 plus 10 x 5 = 1 + 2 + 126 + 50 = 179
If: x/3 + 10 = 15 Then: x = 15
If (x+7) > 10, then x > 3. If (x+7) < 10, then x < 3.
