Which of the following is a number set that contains the number –5? a. integers b. whole numbers c. natural numbers d. irrational numbers

The options are:

a) integer numbers. This is the set of all the whole numbers, positive, negative ad the 0, so this set includes the number -5.

B) Whole numbers: This set is equal to the integer set, so this set also contains -5.

C) Natural numbers: This set only contains the positive whole numbers, so this set does not contain the number -5.

D) irrational numbers: Are those numbers that can no be written ash the quotient between two whole numbers, are numbers that have infinite decimals after the decimal point, so -5 is not belonging to this set.

11

step-by-step explanation:

32.50-7.50=25

225/25=11

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
