Answers

Answer 1

Answer: 5 x² + 7 x + 2 =
= 5 x² + 5 x + 2 x + 2 =
= 5 x ( x + 1 ) + 2 ( x + 1 ) =
= ( x + 1 ) ( 5 x + 2 )
Answer:
D ) None of the above.

Answer 2

Answer:

5 x² + 7 x + 2 =

= 5 x² + 5 x + 2 x + 2 =

= 5 x ( x + 1 ) + 2 ( x + 1 ) =

= ( x + 1 ) ( 5 x + 2 )

Answer:

D ) None of the above.

What is the digit in the thousandths in the number 35.847

Answers

Answer:

Step-by-step explanation:

7 is three places to the right of the decimal point, and therefore the thousandths place

After the decimal place, this is how the order goes:

tenths, hundredths, thousandths

Take the number 1.234

1.(2)34 tenths place

1.2(3)4 hundredths place

1.23(4) thousandths place

2 is in the tenths place

3 is in the hundredths place

4 is in the thousandths place

Collin is buying dirt to fill a garden bed that is a 9ft by 16ft rectangle. If he wants to fill it to a depth of 4 inches, how many cubic yards of dirt does he need? If dirt costs $25 per yard cubed, how much will the project cost?

Answers

Answer:

Cubic yards of dirt needed for project = $1(7)/(9)$ cubic yards

Cost of Project = About $44.44

Step-by-step explanation:

To find number of cubic yards of dirt needed, we need to find the volume.

Rectangular Prism Volume = length * width * depth

Note: Length is 9ft, width is 16ft, depth is 4 inches. We need to change depth to ft. So 4 inches = $(1)/(3)$ feet.

Now finding the volume (in cubic ft) = $9*16*(1)/(3)=48$

We know 3 feet is 1 yard. To convert cubic feet to cubic yards, we have to divide it by (3)^3 = 27. Hence:

$(48)/(27)=(16)/(9)$ cubic yards

* Since dirt is $25 per cubic yard, to find cost, we multiply 25 by 16/9. Hence

Cost of Project = 25 * 16/9 = 400/9 = $44.44

1. How can you use an equation to make a prediction from a pattern? 2. Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.

Answers

So for question 1, Well, using an equation to make a prediction for patterns is pretty easy, really. It is also very efficient. When you look at the pattern, you should be able to make an equation based upon the pattern, or any previous patterns, and using that, you can make an equation to solve or figure out other parts of the pattern.
