28 I feel lucky. Let me know.
The answer for that would be 6x^2 + 8x 13.
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
Funciton form is f(x)=something
basicallly know that f(x) is the output or y
just solve for y
-3x-6y=0
add 3x to both sides
-6y=3x
divide both sides by -6
y=-1/2x
f(x)=(-1/2)x
Answer:
Step-by-step explanation:
5 miles + 16 miles = 21 miles
each mile is 2.50
21 x 2.50 = 52.50
trip is 4.50
52.50 + 4.50 = 57
