Is this sequence arithmetic? If so, what is the common difference (d)? 12, 19, 26, 33

7

Step-by-step explanation:

To find the common difference, take the second term and subtract the first term

19-12 = 7

Check by subtracting the third term and subtract the second term

26-19 = 7

The common difference is 7

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times
