Answer:
P = 2(4x - 5)
Step-by-step explanation:
The formula for solving the perimeter of a rectangle is:
P = 2(L + W), or
P = 2L + 2W
Given the length (L) = 3x - 7, and width (W) = x + 2:
Substitute these values into the perimeter formula in order to solve for x and determine the actual dimensions of the given rectangle.
P = 2L + 2W
Use the distributive property of multiplications (over subtraction and addition, respectively), and distribute 2 into each parenthesis:
P = 2(3x - 7) + 2(x + 2)
P = 6x - 14 + 2x + 4
Combine like terms:
P = 8x - 10
Factor out the common term to reduce the algebraic expresssion into its simplest form:
P = 2(4x - 5)
Therefore, the perimeter of the given rectangle in its simplest form is:
P = 2(4x - 5).
The answer would be option C.

Answer:
The correct option is B
Step-by-step explanation:
We have two coordinates of point A
(-3,-2)
Origin lies between the coordinates. This means that this picture makes a right triangle and it has sides 3 and 2. So we can find the hypotenuse by the Pythagorean theorem:
(Hypotenuse)² = (3)² +(2)²
(Hypotenuse)²= 9 +4
(Hypotenuse)² = 13
Take square root at both sides:
√(Hypotenuse)² =√13
Hypotenuse = √13
Thus the correct option is B....
