The area needs to equal 8 so you need x to be atleast 1.6. Anything over 1.6 would make the area bigger than 8 so the inequality is x>=1.6

Answer:

Step-by-step explanation:

If we want to share £5 to the ratio of 1/3 we should follow this steps :

our ratio is 1/3 so we should add 1 and 3 together to find the total number of parts : 1+3=4
divide the total amount by the number of parts : 5/4 = 1.25
multiply each number in the ratio by 1.25 : 1.25*1=1.25 and 1.25*3=3.75

the answer is 1.25 and 3.75

It was obvious from the beginning that the answer would be the last one since ut had two numbers

following the same steps you get again in the second question :

(a + b)(a ² - ab + b ²) Please help!

Hey there :)

( a + b )( a² - ab + b² )
Let us distribute ( a + b )

a ( a² ) + a ( - ab ) + a ( b² ) + b ( a² ) + b ( - ab ) + b ( b² )
a³ - a²b + ab² + a²b - ab² + b³

We can simplify further:
- a²b + a²b = 0
ab² - ab² = 0

a³ + b³

You can see in the picture I have attached that this is the 7th formula
