Answer:
26.230 Inches per second.
Step-by-step explanation:
Since, Area of square is decreasing at the rate of 43 square inches per second And area is directly proportional to square of the side , So
Its side will be decreasing at the rate of
inches per second .
Now,
Perimeter of square is directly proportional to 4 times of the side of the square.
so Perimeter of square will be decreasing at the rate of 4×
After rounding off to three decimal places we will get 26.230 Inches per second.

Answer:
y = 2 when x =12
Step-by-step explanation:
y = k/x ..............as y varies inversely as x
8 = k/3
k = 8 * 3
k = 24
So,
y = k/x
y = 24/12
y = 2
Answer: x= y+7 / all over 3
Step-by-step explanation:
y= 3x-7
+7. +7
y+7 =3x
÷3. ÷3
y+7/ 3 = x
X should equal -6/11 if I read the equation right
