Answer:

P = (13h+k+6m) cm

Step-by-step explanation:

Given that,

The side lengths of a triangle are :

(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm

We need to find the perimeter of the triangle.

We know that,

Perimeter = sum of all sides

So,

P = (4h + 2k)+(9h + 4m)+(2m - k)

= (4h+9h)+(2k-k)+(4m+2m)

= 13h+k+6m

Hence, the perimeter of the triangle is (13h+k+6m) cm.

Find the coordinates of the orthocenter for XYZ with X(-5,-1) Y(-2,4), Z(3,-1)
V125BC [204]

9514 1404 393

Answer:

  (-2, 2)

Step-by-step explanation:

The orthocenter is the intersection of the altitudes. The altitude lines are not difficult to find here. Each is a line through the vertex that is perpendicular to the opposite side.

Side XZ is horizontal, so the altitude to that side is the vertical line through Y. The x-coordinate of Y is -2, so that altitude has equation ...

  x = -2

__

Side YZ has a rise/run of -1/1 = -1, so the altitude to that side will be the line through X with a slope of -1/(-1) = 1. In point-slope form, the equation is ...

  y -(-1) +(1)(x -(-5))

  y = x +4 . . . . . . . . subtract 1 and simplify

The orthocenter is the point that satisfies both these equations. Using the first equation to substitute for x in the second, we have ...

  y = (-2) +4 = 2

The orthocenter is (x, y) = (-2, 2).

janet is comparing prices of bottled water. one bottle of water costs $1.92 and contains 12 ounces. another bottle of water cost
AnnyKZ [126]

Bottle 1 = $1.92 & 12 ounces

Bottle 2 = $2.40 & 16 ounces

Bottle 1

If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.

$1.92 ÷ 12 = $0.16 per ounce for bottle 1.

Bottle 2

If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.

$2.40 ÷ 16 = $0.15 per ounce for bottle 2.

Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.
