Maria is framing an 8 inch by 10 inch photograph with matting as shown. Which is an expression for the area of the photograph with the mat?

Step-by-step explanation:

Area of the photograph with the mat = area of the photograph + area of the mat

Area of the photograph = length * width = 10*8 = 80 in²

Area of the mat:

Decompose the mat frame into 4 rectangles and 4 squares (these are the corners of x*x dimensions)

The 4 rectangles = 2(8*x) + 2(10*x) = 16x + 20x = 36x

The 4 squares (the corners) = 4(x*x) = 4x²

The area of the photograph with the mat = 80 + 36x + 4x²

Rearrange in standard form:

The expression for the area would be:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
