WILL MARK BRAINLIEST One side of a triangle is twice as long as a second side. The remaining side is 3 larger than the second side. The perimeter is 39m. Find the length of each side.

Step-by-step explanation:

One side of a triangle is four centimeters longer than the shortest side. The third side of the triangle is twice as long as the shortest side. Find the length of all the sides if the perimeter is 40 centimeters.

Let x be the length of the shortest side.

Then the lengths of the other two sides are x + 4 and 2x.

The perimeter of the triangle is x + (x + 4) + 2x.

As the perimeter is 40, we have

x + (x + 4) + 2x = 40

Solving for x, we have

x+ x + 4 + 2x = 40

4x + 4 = 40

4x = 36

x = 9

So the length of the shortest side is 9 cm.

The lengths of the other two sides are:

x + 4 = 9 + 4 = 13 cm

2x = 2*9 = 18 cm

is it 35

step-by-step explanation:

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
