Area = 7x + 3
Perimeter = 14x + 6
Ganezh [65]2 years ago

Answer:

a) 10x² - 3x - 18

b) 14x + 6

Step-by-step explanation:

<u>Given:</u>

length = 5x + 6

width = 2x - 3

Tables usually have rectangular shape.

a) Area of the table

<u>Area of a rectangle</u>

A = length × width

Insert values into formula.

A = length × width

A = (5x + 6) × (2x - 3)

A = 10x² - 15x + 12x - 18

A = 10x² - 3x - 18

b) Perimeter of the table

<u>Perimeter of a rectangle</u>

P = 2 × length + 2 × width

P = 2 × length + 2 × width

P = 2(5x + 6) + 2(2x - 3)

P = 10x + 12 + 4x - 6

P = 14x + 6

Half the sum of a number and 1.75 is −5.1. Enter your answer as a simplified mixed number
musickatia [10]

The unknown number expressed as a mixed fraction is 11 19/20

Let the unknown number be "x"

The sum of the number and 1.75 is expressed as x + 1.75

Half the sum of a number and 1.75 is 1/2(x+1.75)

Equating the result to -5.1 wil give:

1/2(x+1.75) = -5.1

Solve the resulting equation

x + 1.75 = 2(-5.1)

x + 1.75  = -10.2

x = -10.2 - 1.75

x = 11.95

x = 1195/100

x = 11 95/100

Hence the unknown number expressed as a mixed fraction is 11 19/20

Alice has 12 more trees in her garden than Stephen has. After Stephen planted 10 more trees and Alice dug out 4, together they h
Dafna1 [17]

Answer:

Stephen has 9 trees

Alice has 21 trees

Step-by-step explanation:

<u>At the beginning:</u>

Stephen = x trees

Alice = x + 12 trees

<u>At the end:</u>

Alice = (x + 12) - 4 trees

Stephen = x + 10 trees

Total = 36

Then

((x+12)-4)+(x+10)=36\\ \\(x+12-4)+(x+10)=36\\ \\(x+8)+(x+10)=36\\ \\x+8+x+10=36\\ \\2x+18=36\\ \\2x+18-18=36-18\\ \\2x=18\\ \\x=9

Stephen - 9 trees

Alice - 9 + 12 = 21 trees
