Solve for xxx. Write the smaller solution first, and the larger solution second.
Round to two decimal places.
(x + 7)^2 - 11 = 0

Step-by-step explanation:

add to both sides of the equation.

Take the square root of each side of the equation to set up the solution for  

Remove the perfect root factor  

under the radical to solve for  

The complete solution is the result of both the positive and negative portions of the solution.

The result can be shown in multiple forms.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
