What expression is equivalent to -5x^(2)-10x

Answers

Good morning ☕️

Answer:

-5x(x + 2)

Step-by-step explanation:

the key is factoring:

-5x² - 10x = -5x × (x) - 5x × (2)  {here we notice that -5x is a common factor}

               = -5x(x + 2)

Answer:

- 5 {x}^(2) - 10x \n = - 5 x(x + 2)

Fred got a score of 80 on the test. Enter a division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test.

Answers

The division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test is 20 ÷ (-1) = -20.

Let "x" represent the number of questions Fred answered incorrectly on the test.

Since he got a score of 80, then the equation:

Total Questions - Incorrectly Answered Questions = Score

100 - x = 80

To create a division sentence using negative numbers, express this equation in a different form:

x = 100 - 80

Now, subtract:

x = 20

So, a division sentence using negative numbers is:

20 ÷ (-1) = -20

This division sentence represents that Fred answered 20 questions incorrectly on the test.

how to draw an arrow diagram that relates a number (0to9) to the number of lit segments required to display that number?

Answers

The numbers on electronic displays ... like on alarm clocks or digital
watches ... are made out of what's called "7-segment" displays.

For each digit, there's a set of 7 tiny LED's that are laid out
something like this:       _
                                        /_/    
                                       /_/

Then, all of the digits from  0  to  9  can be made just by lighting up
some of the segments, and keeping the rest turned off.

This question is asking for a table that shows how many segments
are lit up to make each digit ... not which ones, but just how many.
This is something the design engineers want to know, so that they
can be sure to provide enough power inside the clock to light up
all the digits.

Look at the picture I attached.  It shows all the digits, 0 to 9, the way
they look in 7-segment displays, and on the right side, the number of
segments that are lit up to make each digit.

I think this is something like what the question is asking for.

Express the fractions 3/4 7/16 and 5/8 with the LCD

Answers

LCD means Least Common Denominator. To find the LCD of 3/4, 7/16, & 5/8, we will first get the multiple of each denominator until we get the same multiple of the three denominator
Multiple of
     i. 4 are 4, 8, 12, 16
     ii. 16 are 16
     iii. 8 are 8, 16

16 is the multiple of 4, 16 and 8. So we will use it now as the LCD of the three given fractions.
We can now express the given fractions with the LCD
     3/4 = 12/16
     7/16 = 7/16
       5/8 = 10/16
