Answer:

$3n^2 + 11n + 6$

Step-by-step explanation:

<u>Key skills: Expanding Polynomials, Multiplication, Combining Like Terms</u>

1) We are given (3n + 2)(n+3) and we need to expand this.

--> You have to use distributive property to expand this.

--> If you multiply everything out it would be --> 3n(n) + 3n(3) + 2(n) + 2(3)

--> 3n(n) = $3n^2$ , 3n(3) = 9n, 2(n) = 2n, 2(3) = 6

--> This means it would be: $3n^2 + 9n + 2n + 6$

Combine the like terms 9n and 2n to make 11n

Your final answer would be $3n^2 + 11n + 6$

Please write the answers with explanation..if nonsense answers I will report.....so answer properly

Musya8 [376]

Answer: 86 degree

Step-by-step explanation:

The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree

P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree

The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree

95 + 160 + 88 + 91 = 434 degree

540 - 434 = 106 degree

180 - 106 = 94 degree

So the last inward degree is 94

Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree

so X is 86 degree

Sorry if this was too confusing:)

What is the area of the rectangle?

den301095 [7]

Answer:

$50\ units^{2}$

Step-by-step explanation:

Plot the figure to better understand the problem

see the attached figure

we know that

If the figure is a rectangle

then

$AB=CD \\AD=BC$

The area of the rectangle is equal to

$A=B*h$

where

B is the base

h is the height

the base B is equal to the distance AB

the height h is equal to the distance AD

Step 1

Find the distance AB

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,5)\\B(0,-5)$

substitute the values

$d=\sqrt{(-5-5)^{2}+(0+5)^{2}}\\d=\sqrt{(-10)^{2}+(5)^{2}}\\dAB=\sqrt{125}\ units$

Step 2

Find the distance AD

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,5)\\D(-1,7)$

substitute the values

$d=\sqrt{(7-5)^{2}+(-1+5)^{2}}\\d=\sqrt{(2)^{2}+(4)^{2}}\\dAD=\sqrt{20}\ units$

Step 3

Find the area of the rectangle

$A=AB*AD$

we have

$dAB=\sqrt{125}\ units\\dAD=\sqrt{20}\ units$

substitute

$A=\sqrt{125}*\sqrt{20}\\A=\sqrt{2,500}\\A=50\ units^{2}$
