Answer:
In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line
Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.
16
ANSWER

EXPLANATION
The given expression is

The greatest common factor is 2.
We factor 2 to obtain:

The expression in the parenthesis is prime.
This means that the quadratic expression in the parenthesis cannot be factored.
Hence the completely factored form is:

Dilation since one image is bigger than the other
No solution because
Y+7=Y-3
-y. -y
y cancels out so you are left with
7= -3
