Answer 1

Answer:

Answer:

The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A plz mark me brainlest

Step-by-step explanation:

* Lets explain how to solve the problem

- We have a statement:

" six less than nine times the sum of a number and eight"

- When we solve we will start by the last part

- The last part is the sum of a number and 8

- Assume that the number is n

∵ The sum is the answer of adding

∴ The sum of a number and eight is ⇒ n + 8

- Nine times the sum

∵ The sum is n + 8

∵ Nine times means multiply the sum by 9

∴ Nine times the sum is ⇒ 9(n + 8)

- Six less than nine times the sum

∵ Nine times the sum is 9(n + 8)

∵ Six less than means subtract 6 from nine times the sum

∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6

* The expression is 9(n + 8) - 6

- Lets evaluate the expression when n = 5

∵ 9(n + 8) - 6

∵ n = 5

∴ The value = 9(5 + 8) - 6

∴ The value = 9(13) - 6

∴ The value = 117 - 6

∴ The value = 111

* When n = 5 the value of the expression is 111

Parallel = has same slope
On points( 3,4) (-2,2)

Find the slope of the other points:
(-2,-5) and (-7,-3)
(-3-(-5))/(-7-(-2)) = 2/-5 = -2/5

(-1, 1) and (-6, -1)
(-1-1)/(-6-(-1)) = -2/-5 = 2/5

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answers

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 7 cm in diameter. How many square inches will she need to frost one dozen cookies?

Answers

Answer:

51.92 square inches

Step-by-step explanation:

Area of a circle = (pi)(r^2)

if the diameter is 7, the radius is 3.5

A = 3.14 x 3.5

A = 10.99 cm^2 for one cookie

10.99 x 12 for a dozen = 131.88 cm^2

converting cm to inches, you divide by 2.54

131.88/2.54 = 51.92 square inches.
