its is -1. Even though the 6 is an absolute value. |6| is just 6-7
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
Area of square painting is 400 square inches.
Let the side of square painting is = a inch
So the area of square painting is =

square inch.
So


Length of wood trim to need to go around the painting is equal to the perimeter of square painting .
So the perimeter of square painting is = 4 * (side)
= 4* 20 = 80 inch.
So the required length of wood trim is = 80 inch.
Answer:
perimeter is 36 inches and the area is 32 square inches
