2. Determine all real values of x such that: (x + 8) = (2x +16)?.

x = -8

Step-by-step explanation:

(x + 8) = (2x + 16)

x + 8 = 2x + 16

take x from both sides 8 = x + 16

now take 16 from both sides -8 = x

x = -8

x=-8

Step-by-step explanation:

To solve, you can factor the right side.

x+8 = 2(x+8)

Now if you try to divide by x+8, you will get this.

0 = 2

So this equation has no solutions - but wait!

You have to remember domain when dividing by an algebraic expression!

Since 0 is never equal to two, you must acknowledge that when dividing by an algebraic expression, the expression may be equivalent to zero. In this case, x+8 is equal to zero is x=-8, so the answer is x=-8.

Hopes this helps!

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
