Find the measure of the exterior angle. (I'm assuming it's easy I'm just bad at math.)

60+x+9=2x then solve for x. x=69
plug in 69 to the exterior angle which is 2x. 2(69)=138°

You will do area for a triangle . when multiplying with the (x+9) you will just multiply the number infront of the parentheses by both the x and the 9. for example the 60 would be 60(x+9) which would be 60x+540

4(x-5) +2 =x+3 <br><br> I need help on this ! I don’t get it picture above !
algol [13]

Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3       Subtract x from each side. Now, we can get x to only one side.

<u>-x       -x</u>

3x-18=-3         Add 18 to both sides.

  <u>+18 +18</u>

3x=-15            Divide both sides by 3.

<u>/3   /3</u>

x=-5

I hope this helped you!! Have a great day c:

Answer:

<em>- 112 + 100 n</em>

Step-by-step explanation:

a_{n} = a_{1} + (n - 1 )d

~~~~~~~

a_{1} = - 12

d = 100

a_{n} = - 12 + 100( n - 1 )

a_{n} = - 12 + 100n - 100

a_{n} <em>= - 112 + 100 n</em>

World war 1 lasted from August 4th 1914 until November 11th, 1918. During this time an estimated 10 million lives were lost. Abo

The question is so dry, mechanical, and devoid of emotion
that it's terrifying.

There is no way to assign a number to "How many people were
dying per day", and I would prefer not even to think about it in
those terms.

-- The period of time from August 4, 1914 until November 11, 1918 is 1,560 days.

-- The "average", or better, the "unit rate" of 10 million events in 1,560 days
is the quotient

                   (10,000,000 events) / (1,560 days) 

               =  6,410.3 events per day

               =     267.1 events per hour

               =       4.45 events per minute.


Reciprocally, this is a unit rate of 

                  13.48 seconds per event,
                  sustained continuously for 4.274 years !

When will we ever learn ! ?

vlada-n [284]
200-3w = 300-5w

Where w is the number of weeks

Rearrange and reduce:
-3w + 5w = 300-200
2 w = 100
w = 100/2 = 50 weeks
