Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.

x = negative 21 over 2
x = −6
x = negative 6 over 5
x = −12

Option D is correct.

x = -12

Step-by-step explanation:

Solve:  

We can write 49 as:

using exponent rules:

Apply this rules on the given equation:

Simplify:

On comparing both sides we get;

Subtract 2x from both sides we get;

x = -12

Therefore, the value of x is -12

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
