6n + 28 because the difference is 12 so if u half that to get the second it’s 6 hence 6n and then u have to add 6 to 22 to get 28 and it’s a positive number so therefore the expression is 6n+ 28

Answer:

  an = 22 -6(n -1)

Step-by-step explanation:

The first term of the sequence is given as a1 = 22. The general term of an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . n-th term for first term a1 and common difference d

The third term will be ...

  a3 = 10 = 22 +d(3 -1)

Then the common difference is ...

  10 -22 = 2d

  -12/2 = d = -6

__

Putting the known values into the formula for the general term, it becomes ...

  an = 22 -6(n -1)

__

This can be simplified to ...

  an = 28 -6n

To find the area of the rectangle, do A=lw which is 4x13=52. to find the area of the triangle, first find the height. this is 13-6=7. now do A=bh/2 which is (5x7)/2=17.5. 17.5+52=69.5 which is your answer. DONT OPEN ANY LINKS ON HERE, ITS A VIRUS

Need answers ASAP please and Thankyou!
amid [387]

Answer:

A = 65deg

B = 78deg

Step-by-step explanation:

It's a triangle, so we know that the sum of angles is 180deg

x + (2x - 9) + (2x + 4) = 180

5x - 5 = 180

5x = 185

x = 37

Measure of angle A = (2*37 - 9)deg = 65deg

Measure of angle B = (2*37 + 4)deg = 78deg

kompoz [17]

Answer:

Step-by-step explanation:

b(n)=4-6(n-1)

let n=4

b(4) = 4 - 6(4-1)

b(4) = 4-6*3

b(4) = 4-18

b(4) = -14
