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
Answer:
okay, I'll explain how to do it.
y = 4x
so make a table
-1. -4
0. 0
1. 4
plot those points and draw a line through them.
let's plot some points to start.
