2. Your number is a negative integer, so belongs to the sets ...

Natural numbers are positive integers, also called "counting numbers," 1, 2, 3, and so on. Whole numbers are the natural numbers and zero. Irrational numbers are numbers that cannot be expressed as the ratio of an integer to a positive or negative natural number. Written in decimal, irrational numbers have a non-repeating fractional part of infinite length.

3. The phrase "6 times the difference of b and p" can be written as

... B.) 6(b-p)

4. 5(14 -2)²/2

... = 5·12²/2

... = 5·144/2

... = 720/2

... = 360

The appropriate choice is ...

... D.) 360

5. Put the values where the variables are, then do the arithmetic.

... u +xy = 18 +10·8 = 18 +80 = 98

The appropriate choice is ...

... C.) 98

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
