Find the perimeter P of ▱JKLM with vertices J(−3,−2), K(−5,−5), L(1,−5), and M(3,−2). Round your answer to the nearest tenth, if
Bezzdna [24]

Given:

Vertices of JKLM are J(−3,−2), K(−5,−5), L(1,−5), and M(3,−2).

To find:

The perimeter P of a parallelogram JKLM.

Solution:

Distance formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using distance formula, we get

JK=\sqrt{\left(-5-\left(-3\right)\right)^2+\left(-5-\left(-2\right)\right)^2}

JK=\sqrt{\left(-5+3\right)^2+\left(-5+2\right)^2}

JK=\sqrt{\left(-2\right)^2+\left(-3\right)^2}

JK=\sqrt{4+9}

JK=\sqrt{13}

Similarly,

KL=\sqrt{\left(1-\left(-5\right)\right)^2+\left(-5-\left(-5\right)\right)^2}=6

LM=\sqrt{\left(3-1\right)^2+\left(-2-\left(-5\right)\right)^2}=\sqrt{13}

JM=\sqrt{\left(3-\left(-3\right)\right)^2+\left(-2-\left(-2\right)\right)^2}=6

Now, perimeter P of ▱JKLM is

P=JK+KL+LM+JM

P=\sqrt{13}+6+\sqrt{13}+6

P=2\sqrt{13}+12

P=2(3.61)+12

P=7.22+12

P=19.22

P\approx 19.2

Therefore, the perimeter P of ▱JKLM is 19.2 units.

What is this plzz need help for math homework it is very hard
evablogger [386]
I believe the correct answer is “a5+2” or, like the question says to write it, “7 L(centimeters.)” this is because using the normal steps for equations, you add up how many “a”s you have total. Then you combine “-1 and +3”, which gives you positive 2. Then you add 5+2 which gives you 7. Hope this helped! :) please mark as Brainliest if the answer is correct!

I NEED HELP ON NUMBER 8 PLSSSS
antiseptic1488 [7]

Answer:

17 inches

Step-by-step explanation:

for this equation, we know the length and the width of the water and the volume. we can use this information to solve for the height of the water.

V = 2244 cubic inches

l = 12 in

w = 11 in

V = l * w * h

2244 = 12 * 11 * h

2244 = 132h

17 = h

the height of the water is 17 inches.

For f(x) = 3x + 1 and g(x) = x2 - 6, find (f + g)(x).
Tasya [4]

Answer:

x^2+3x-5

Step-by-step explanation:

f(x) = 3x + 1

g(x) = x^2 - 6,

(f + g)(x)= 3x + 1 +x^2 - 6,

Combine like terms

        = x^2+3x-5
