Simply the expression 3(6+7n)+(-5)

13+21n

Step-by-step explanation:

first you distribute:

3*6, 3*7n

which concludes to:

18+21n+(-5)

then you combine like terms:

18+(-5)

which gives you:

13

concluding equation:

13+21n

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
