Dana said that speed, s, could be either an independent or dependent variable. Write a situation where speed, s, is an independent variable. Then write a situation where speed, s, is a dependent variable.

As dependent variable;

speed = distance/time

As independent variable

distance = speed * time

Step-by-step explanation:

When we say dependent variable, we mean that the value of the speed depends on some values.

When we say independent, we mean the value of some quantities is dependent on the speed.

As dependent variable;

speed = distance/time

As independent variable

distance = speed * time

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
