Answer:

5x-2y

Step-by-step explanation:

2x-(3y-2x-y-x)

Distribute Negative Sign

2x+-1(3y-2x-y-x)\\2x+-1(3y)+-1(-2x)+-1(-y)+-1(x)\\2x+-3y+2x+y+x

Combine like terms:

(2x+2x+x)+(-3y+y)\\5x+-2y\\5x-2y

5x-2y is your final answer.

A blue die and a red die are thrown. Each die has six sides, labeled 1 through 6. The dice are fair, so each outcome is equally
lidiya [134]

Answer:0.138

Step-by-step explanation:

Given

A blue die and a red die is rolled once such that each face is marked with different number

Favorable outcome of getting 6 is

(5,1) , (1,5) , (4,2) , (2,4) , (3,3)

Total outcomes =36

Probability of getting a sum of 6 is =\frac{5}{36}=0.138

How would I set up the equation to find mRQS on this circle?
Leni [432]
MRQS=360-mSR. or mRQS=31x+13...To solve the measure of the minor arc RQS you would use this... 31x+13+(6+18x/2. )=360.

Calculate the perimeter and area of the triangle formed by the coordinates K (-4,-1) ,L(-2, 2), and M (3,-1).
Y_Kistochka [10]

Perimeter = 16.4 units

Using the heron's formula, Area ≈ 10.4 units².

<h3>What is the Heron's Formula?</h3>

The heron's formula is used to find the area of a triangle with known side lengths of all its three sides, a, b, and c. The heron's formula is given as: Area = √[s(s - a)(s - b)(s - c)], where s = half the perimeter of the triangle

s = (a + b + c)/2.

Given the following:

K (-4,-1) ,

L(-2, 2),

M (3,-1)

Use the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, to find KL, LM, and KM.

KL = √[(−2−(−4))² + (2−(−1))²]

KL = √13 ≈ 3.6 units

LM = √[(−2−3)² + (2−(−1))²]

LM = √34 = 5.8 units

KM = √[(−4−3)² + (−1−(−1))²]

KM = √49 = 7 units

Perimeter = 3.6 + 5.8 + 7 = 16.4 units

Semi-perimeter (s) = 1/2(16.4) = 8.2 units

KL = a ≈ 3.6 units

LM = b = 5.8 units

KM = c = 7 units

s = 8.2

Plug in the values into √[s(s - a)(s - b)(s - c)]

Area = √[8.2(8.2 - 3.6)(8.2 - 5.8)(8.2 - 7)]

Area = √[8.2(4.6)(2.4)(1.2)]

Area = √108.6336

Area ≈ 10.4 units²
