y = .0775x + 700
y = .0775(4,000) + 700
y = 310 + 700
y = 1,010

The group of those shapes are parallelograms
Answer:
(21x+168)cm²
Step-by-step explanation:
If the expression 2 1 (x + 8) represents the area of the model bridge, where 2 1 is the width, in centimeters, and (x + 8) represents the extended length, the expression that is equivalent to 21(x+8) can be gotten by expanding the function. The expansion of the function will give the area of the rectangular model bridge as shown;
21(x+8) = 21x+ 168
The expression equivalent to 21(x+8) is therefore (21x+68)cm²
Note that the the unit of the value and function given is in cm therefore the unit of their equivalent expression will be in cm²
