Mr. Howard planted a new garden. The garden is 15 feet long and 4 feet wide. What is the perimeter of mr. Howard's garden?
MrRissso [65]

Answer:  38 feet

Step-by-step explanation:

Based on the dimensions of the garden, we can infer that it a rectangular garden because one side is longer than the other.

The perimeter of a rectangle is calculated as:

= (2 * length) + (2 * width)

= (2 * 15) + (2 * 4)

= 30 + 8

= 38 feet

Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level
jek_recluse [69]

Answer:

Step-by-step explanation:

Is this the entire question? Some of it makes no sense without a diagram or something.

To get rid of A you actually have to solve the equation.

7h – 5(3h – 8) = –72        Remove the brackets

7h - 15h + 40 = - 72          Combine the like terms

- 8h + 40 = - 72                Subtract 40 from both sides

- 8h = -112                        Divide by -8

    h = 14

Well the depth is a whole number so A is true.

We don't know anything about time. But the answer is positive.

C is false because B is true.

We don't know exactly what the depth of the well is.

I would pick A, but you need the entire question.
