30 points! the figure below (attached picture) represents a rectangular painting with a rectangular frame. the gray section in the figure below represents the painting, and the white section in the figure below represents the frame.

part a
write an expression in standard form that represents the area, in square feet, of the painting.

part b
write an expression in standard form that represents the area, in square feet, of the frame.

part c
write an expression in standard form that represents the perimeter, in feet, of the painting.

Part A : Area = Xft . X ft

Part B: A= 6ft . 4ft

Part C: P = xft +x ft + xft +x ft

Step-by-step explanation:

Hi, for part A and part B we have to apply the area formula (for a rectangle)

Area = L . W

Where:

L: Lenght

W: Width

Replacing with the values given:

Part A= Area of the painting (grey area)

A = Xft . X ft

Part B = Area of the frame (white section)

A= 6ft . 4ft

For part C we have to apply the perimeter formula:

Perimeter = 2 L + 2 W

Replacing with the values given:

P = 2xft +2xft

or

P = xft +x ft + xft +x ft (sum of all sides)

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
