Find the perimeter of the triangle in units. Round to two decimal places as necessary.

Dimas [21]

Answer:

54.56 units

Step-by-step explanation:

The vertices are:

K(-12,2), L(-7,12), J(3,-10)

Find the sides using distance formula:

KL = $\sqrt{(-7+12)^2+(12-2)^2} = \sqrt{125}$ ≈ 11.18
LJ = $\sqrt{(3+7)^2+(-10-12)^2} = \sqrt{584}$ ≈ 24.17
KJ = $\sqrt{(3+12)^2+(-10-2)^2} = \sqrt{369}$ ≈ 19.21

Find perimeter:

P = KL + LJ + KJ
P = 11.18 + 24.17 + 19.21 = 54.56 units

translate this into an expression: the quotient of a number, x, and 8, could you please explain it to me?

Xelga [282]

Answer:

x/8

Step-by-step explanation:

First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.

The first number listed is x. Therefore, we have

x/something else.

Next, we are given "and 8", so we have x/8 as our expression
