Set up your parentheses, and put x in the front of both because x is squared. It should look like this: (x     )(x     ). Next, you find notice that one sign must be positive, and one must be negative. Then, you find the factors of 36. 6 and 6, 3 and 12, 1 and 36, 18 and 2, and 9 and 4. You then guess and check with the different signs and factors what will get you back to the trinomial using the FOIL method. When you do this, you should get (x-9)(x+4).

Write 2350 million in standard form
AleksAgata [21]

we know that

<u>Standard Form</u> is also known as Scientific Notation, is a method of writing numbers that accommodates value excessively large or small to be suitably written in Standard Decimal Notation

in this problem we have

2,350\ million

Remember that

1\ million=1,000,000

so

2,350\ million=2,350*1,000,000=2,350,000,000

<u>convert to standard form </u>

2,350,000,000=2.35*10^{9}

therefore

<u>the answer is</u>

2.35*10^{9}

After painting his porch jamil has 1/4 of a can of paint remaining the can has a radius of 8cm and a height of 20cm he wants to
ozzi

Answer:

12.8 cm

Step-by-step explanation:

Radius of the can is 8 cm and height is 20 cm.

It is given that after painting his porch Jamil has \frac{1}{4} of a can of paint remaining. So, first we need to find the total amount of paint in the can.

Total amount of paint in the can is \text{Base area}\times\text{height}

So, paint in the can =\pi r^{2}\times h

=\pi (8)^{2}\times 20

Now \frac{1}{4}  of the can is \frac{1}{4}\times \pi (8)^{2}\times 20

=320\pi cubic cm.

Now, let the height of the smaller can be <em>h</em> cm.

Radius of the smaller can is 5 cm.

As, the paint is poured into the smaller can the volume of both the cans will be same.

\pi (5)^{2}\times h=320\pi

h=\frac{320\pi}{25\pi}

h=12.8

Hence, height of the smaller can to hold the paint must be 12.8 cm.
