Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
Answer: 4
Answer:
B
Step-by-step explanation:
If you graph y^2/361 + x^2/169=1 you will get the same graph depicted in the equation.
You can use a table like this x -1 0 1 2
y 0 2 4 6
and a T table
-2x-x+8
Step 1) -2x-1x+8
step 2) (-2-1)x+8
Step 3) -3x+8
Answer: -3x+8 :)
474 divided by 9
Turn 474 into 450 because 45 is a multiple of 9
9 x 5= 45
9 x 50= 45
Therefore 474 would be 450.
So,
450 divided by 9 equals 50
