PLS HELP!!: A rectangular garden measures 3 feet by 6 feet. The gardener wants to triple the area of the garden by extending both the width and length by the same distance . What should the dimensions of the new garden be?

9ft by 18ft

Step-by-step explanation: So triple means 3times that number

so what you do is easy 3•3=9 thats how you get 9ft and 6•3=18 and thats how you get 18ft.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
