The process of manipulating one or more independent variables and measuring their effect on one or more dependent variables while controlling for the extraneous variables is called an experiment. a. true b. false

Ok, let's think our dependent variable like the position of a car with velocity of 50km/h, and our independent variable the time.

so, you can choose any time you want, and for each time, the car will be in a different position, so the position is a variable dependent of the time.

let's suppose you don't know the velocity of the car.

first you see the position at a time t₁ and the position is r₁.

then you see the position at time t₂, and the result is r₂.

here you changed the independent variable and observed how the dependent variable changed. And in this case, with the 4 numbers you observed you can obtain the velocity of the car.

So yes, you can call it an experiment.

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )
