Aaron wants to mulch his garden. His garden is x^2+18x+81 ft^2 One bag of mulch covers x^2-81 ft^2 . Divide the expressions and simplify to find how many bags of mulch Aaron needs to mulch his garden.

Step-by-step explanation:

Given

Garden:

One Bag:

Requires

Determine the number of bags to cover the whole garden

This is calculated as thus;

Expand the numerator

Express 81 as 9²

Evaluate as difference of two squares

Hence, the number of bags is

x/3-10=8

x/3=18

x=48

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
