Yes, it's me again! How would you write the expression that represents the perimeter of a rectangle measuring 4 x - 4 + 7 x + 1
Would it be -4 + 1 = - 5
No.
2(11x - 3) = P
Thank You Ms. Sue, I'll get the hang of this eventually!!!!!
You're welcome. :-)

You're welcome.
To find the perimeter of a rectangle, you need to add up the lengths of all its sides.
A rectangle has two pairs of sides, where each pair has the same length. Let's assume that the lengths of the two pairs of sides are represented by variables 'a' and 'b'. Therefore, the perimeter (P) of the rectangle can be found by using the following formula:
P = 2a + 2b
In your case, the expression representing the length of one pair of sides is given as 4x - 4, and the expression representing the length of the other pair of sides is 7x + 1.
Therefore, the perimeter (P) of the rectangle can be found by substituting these expressions into the formula:
P = 2(4x - 4) + 2(7x + 1)
Multiplying, we get:
P = 8x - 8 + 14x + 2
Combine like terms:
P = (8x + 14x) + (-8 + 2)
P = 22x - 6
So, the correct expression representing the perimeter of the given rectangle is 22x - 6. It is important to ensure all like terms are combined when simplifying algebraic expressions.
