A. Just add the given sides.

8y^2+8y-10 is the answer.

B. The perimeter of any shape is all the sides added together. The perimeter given is the perimeter of the quadrilateral, and we are to find the other side. We are given values of three sides. We can find the value of the other side by subtracting the sum of those three sides from the total perimeter:


(22y^3+10y^2+10y-17)-[(4y+2y^2-3)+(-4+2y^2+2y)+(4y^2−3+2y)]

When simplified, you get 22y^3+2y^2+2y-7.

C. The polynomials are closed under addition and subtraction as the result is another polynomial. It can be justified by parts A and B.



Hope this helps.

A. total length of side 1-3 = side 1 + side 2 + side 3

Side 1: 4y + 2y2 − 3

Side 2: −4 + 2y2 + 2y  

Side 3: 4y2 − 3 + 2y

so total = 8y^2 + 8y - 10


B. perimeter = sum of side 1-4

so length of side 4 = perimeter - total of side 1-3

= 22y3 + 10y2 + 10y − 17 - (8y^2 + 8y - 10)

= 22y^3 + 2y^2 + 2y - 7


C. they are close for addition and subtraction. Part A and B show that.

Natasha_Volkova [10]

Answer:

-6 ≤x

Step-by-step explanation:

3x-2≤5(x+2)

Distribute

3x-2≤5x+10

Subtract 3x

3x-2-3x≤5x +10-3x  

-2 ≤2x+10

Subtract 10 from each side

-2-10 ≤2x+10-10

-12 ≤2x

Divide by 2

-12/2≤2x/2

-6 ≤x

5^=1 ÷ 652 tell the answer
JulsSmile [24]

Answer:

n = - 4

Step-by-step explanation:

note that 625 = 5^{4} , then

5^{n} = \frac{1}{5^{4} } = 5^{-4}

Since the bases on both sides are equal, both 5 then equate the exponents

n = - 4

What is the means-to-MAD ratio of the two data sets, expressed as a decimal? Data set Mean Mean absolute deviation (MAD) 1 10.3
aleksklad [387]
Mean -to-MAD ratio is the division of the Mean by the Mean Absolute Deviaion (MAD). For the set 1, mean / MAD is 10.3 / 1. 6 = 6.4375; and for the set 2, Mean / MAD is: 12.7 / 1.5 = 8.467. This is a measure of disperssion of a set of values. MAD is calculated as the sum of the absolute differences of the values and the mean.
