3. You want to put siding on a house that is 18 meters long and 14 meters wide. The walls
are 4 meters high. There are two windows, each measuring 1.5 m by 2 m and a door
that is 1 m wide and 2.5 m high. The siding costs $12.50/m2. How much will it cost to
side the house? (10.3 Meeting) (10.5 Mastery)

Step-by-step explanation:

Lets find the area of the siding

18*14*4, this is 1008

But there are 3 objects

there are two windows that are 1.5 by 2m

Each window has two 1.5 length sides and 2, 2m sides

adding those together is 3 by 4m

then adding these together is 7

The perimeter of the window is 7

then we do that again which would get us to the other window also having a perimeter of 7

adding those together we have a total perimeter of 14

Then we have a door that is 1x2.5

there is 2 2.5 and 2 1 so

1 + 1 is 2

2.5 + 2.5 is 5

thats 7 total

14 + 7 is 21

The total perimeter of those objects is 21

The total area of the siding that we needed before was 1008

From here honestly I dont know what to do because i dont know how area and perimeter work together like this

here u go

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
