How do you solve 2(x+7)+x=20
alexira [117]
2(x+7) + x=20
(2)(x) + (2)(7) + x=20  Distribute 
2x+14 + x =20
(2x+x) + (14) =20  Combine Like Terms 
3x+14=20 
    - 14  -14             Subtract 14 from both sides 
3x = 6 
3x/3 6/3                  Divide Both Sides by 3 
 
x = 2

(ab² + 13b - 4a) + (3ab² + a +7b)
Natalija [7]

Answer:

4ab² + 20b - 3a

Step-by-step explanation:

This question most likely asks us to simplify the expression, as factoring is not possible...

(ab² + 13b - 4a) + (3ab² + a + 7b),

ab² + 13b - 4a + 3ab² + a + 7b,

ab² + 3ab² + 13b + 7b - 4a + a,

Solution : 4ab² + 20b - 3a

What is the square root of –16?<br><br><br><br> –8i<br><br> –4i<br><br> 4i<br><br> 8i
Ad libitum [116K]

we know that

i^{2} =-1

we have

\sqrt{-16} =\sqrt{(-1)*(16)} =\sqrt{(-1)*(4^{2})}

substitute the value of i^{2}=-1 in the expression above

\sqrt{(-1)*(4^{2})}=\sqrt{i^{2}*4^{2}} \\ \\= 4i

therefore

<u>the answer is</u>

4i
