Answer:

9x^2 - 10x -4

Step-by-step explanation:

It is set up like this

9x^2 - 8x

- (x-2)2

First solve (x-2)2

the answer is (2x-4)

so now you can do this instead

9x^2 - 8x

- 2x - 4

----------------------------------

9x^2 - 10x +4

9x^2 minus zero is 9x^2

-8x-2x is -10x

0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive

A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus

like this

9x^2 - 8x

+ -2x + 4

----------------------------------

9x^2 - 10x +4

Given

Caisha has a circular garden with a radius of 4 ft.

She needs to put a layer of soil on top. e

Each bag of soil covers 9.42 square feet.

<h3>What is the radius of a circular garden?</h3>

The radius of the circular garden is equal to the pie times of the square of the radius.

The radius of the circular garden is;

$\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24$

Therefore,

The number of bags of soil will she need to buy is;

$\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx$

Hence, she needs to buy 6 bags of soil.
