The expression which shows the total area of the picture and frame is +320.
Given that the width of the frame is x ,length horizontally be 20 inches and vertically be 16 inches.
We are required to find the expression which shows the total area of the picture and frame.
Expression is basically a combination of numbers, symbols, coefficients, determinants, indeterminants,etc. and are mostly not found in equal to form.
Since we are given that the width of the frame be x, So,the are of only frame will be :
Area of frame=20*x*2+16*x*2+x*x
=40x+32x+
=+72x
Area of picture=20*16=320
The expression which shows the total area of the picture and frame is +320.
Hence the expression which shows the total area of the picture and frame is +320.

The relationship between 3x+4y=1 and 6x+8y=2 is that they are parallel lines.
<h3>What is the slope-intercept form of an equation?</h3>Any linear equation has the form of y=mx+b
m is the slope of the equation
b is the y-intercept
The easiest way to see the relationship between the two lines is to transform them both into slope-intercept form, which is y=mx+b.
Equation 1 can be rewritten as
3x+4y=1
4y=1-3x
y=
Equation 2 can be rewritten as:
6x+8y=2
8y=2-6x
y =
Y=
In this form, we can easily identify that both lines have a slope of , but that they have different y-intercepts. Lines will equal slopes but different y-intercepts are parallel.
Therefore, the lines are parallel.
