What are three consecutive even integers whose sum is 66

Smallest integer: 20

Middle integer: 22

Largest integer: 24

Step-by-step explanation:

Denote the smallest integer as "x"; hence the next integer will be "x + 2", and the third will be "x + 4".

Using the information, set up an equation:

x + x + 2 + x + 4 = 66

Simplify

x + x + 2 + x + 4 = 66

3x + 6 = 66

Inverse operations

3x + 6 = 66

    -6      -6

3x = 60

/3     /3

x = 20

Smallest integer: 20

Middle integer: 22

Largest integer: 24

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
