-5 feet per minute * 12 minutes = -60 feet descended over a course of 12 minutes

-1260 - 60 = -1320 ft below sea level

kati45 [8]

Answer: 12 sections of 1/16 acre

Step-by-step explanation:

We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.

This is equal to the quotient between 3/4 and 1/16

Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:

(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)

The quotient we want to solve is:

(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12

Then you can have 12 sections of 1/16 acre

Which of the following is the square of a binomial?
anyanavicka [17]

All options except Option D , a² + b²  , is the square of the binomial.

<h3>What is a Binomial ?</h3>

A polynomial that contains only two term is called a Binomial.

The sum of square of a binomial is the sum of square of the first term , square of second term and twice of the product of the first and second term.

(a+b)² = a² +b² +2ab

(a-b)² =  a² +b²-2ab

The options have to be broken down into this form to check whether they are square of a binomial

Option A : 4m² - 6mn + 9n² = (2m -3n)²

Option B:  16x² + 24xy + 9y²=(4x+3y)²

Option C : c²- 2cd - d²=(c-d)²

Option D : a² + b² cannot be written as the square of binomial.

All options except Option D is the square of the binomial.
