Answer:

P.E.M.D.A.S, Then combine like terms.

Step-by-step explanation:

(2n +2)(6n + 1)

P.E.M.D.A.S tells you to do parenthasis first, but because both equations are in parenthasis, follow the equation in order. Next, combine like terms.

(2n + 6n)(2+1)

2n + 6n = 8n

2 + 1 = 3

Isolate the variable

8n * 3

8n/ 8 = n

8/ 3 = 2.6

n = 2.6

If the points (2,7),(-3,3) and (5,1) are the vertices of a triangle ,find the length of the median drawn through the first verte

Bingel [31]

Answer:

$\sqrt{26}$ units

Step-by-step explanation:

The median is the line segment connecting the vertex with the midpoint of the opposite side.

The midpoint has coordinates:

x = (-3 + 5)/2 = 2/2 = 1
y = (3 + 1)/2 = 4/2 = 2

Use the distance formula to find the distance between points (2, 7) and (1, 2):

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
$d=\sqrt{(1- 2)^2+(2-7)^2} =\sqrt{1+25} =\sqrt{26}$

Round 71.916476787 to 1 decimal place.

jasenka [17]

Answer:

71.9

Step-by-step explanation:

Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit.
