The expression which is not equivalent to (8 + (n - 4)) is (12+n) and this can be determined by using the arithmetic operations.
Given :
Expression - 8 + (n - 4)
To simplify the given expression following steps can be used:
Step 1 - Rewrite the given expression.
= (n - 4) + 8
Step 2 - Now, remove the parenthesis in the given expression.
= n - 4 + 8
Step 3 - Now, write 8 as the addition of 4 and 4.
= n - 4 + 4 + 4
Step 4 - Subtract 4 by 4.
= n + 4
Therefore, the correct answer is (12+n).

Answer:
10
Step-by-step explanation:
LN = 4 + x - 8 = x - 4
LS = 3 + x - 5 = x - 2
By intersecting secants theorem:
Answers would be x = -6 , x = -2/3
Answer
8x-10
Step-by-step explanation:
Length=x+2
Breadth= 3x-7
Perimeter= 2(length+breadth)
Perimeter of the given rectangle= 2(x+2+3x-7)
=2(4x-5)
=8x-10
