5286 ft

Step-by-step explanation:

The question has been answered but I guess you need an explanation on how the answer was derived.

Given Parameter

1 mi 72 inch

Required

Convert to feet

To complete this conversion, we need to split the given data into 2.

1 mi and 72 inch

= 1 mi + 72 inch

Then we convert them separately.

From unit of standard conversion;

1 mile (1 mi) is equivalent to 5280 ft

Also from unit of standard conversion

1 inch = 1/12 foot

So, 72 inches will be

=> 72 * 1/12 ft

=> 72/12 ft

=> 6 ft

Now that we have the equivalent of 1 mi and 72 in, in foot.

We can then write the following;

1 mi + 72 inch

=> 5280 ft + 6 ft

=> 5286 ft.

Hence, 1 mi 72 inch is equivalent to 5286 ft

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
