Answer:

D

Step-by-step explanation:

1. x^2+12x+20=0

2. x^2+10x+2x+20=0

3. x(x+10)+2(x+10)=0

4. (x+10)x(x+2)=0

5. x+10=0

   x+2=0

C.) A <span>dilation with a scale factor of 4, with center of dilation at the origin

Here, You can either draw the figure or compare the coordinates, 
B = (4, 4) then B' = (1, 1)
C = (-4, 4) then C' = (-1, 1)
D = (-4, -4) then D' = (-1, -1)
E = (4, -4) then E' = (1, -1)

So, Every coordinate is reducing by 4th factor... Hence, dilation factor is 4 about the origin

The larger of two positive integers is three more than the
katrin2010 [14]

Answer:

y=x+4

Step-by-step explanation:

So, let's start with the fact that we have two numbers. Let's call one of them "x" and the other one "y." Let's also assume that "y" is the larger number and "x" is the smaller number.

 

We know that both of them added together (the sum) gives us 74. Mathematically, that means:

 

x+y=74.

 

We also know that the larger number ("y") is 4 more than the smaller number ("x"). Another way to say this is, if you have the smaller number and add 4 more to it, you'll end up with the larger number. Mathematically, this means:

 

y=x+4

 

Since we know that y=x+4, we can put "x+4" into the first equation for "y", giving us:

 

x+(x+4)=74

 

Simplifying gives us:

 

2x+4=74

   -4   -4

  ---------

2x=70

---  ---

2    2

 

 

x=35

 

Since we now know that x=35, and we know that y=x+4, we now know that:

 

y=(35)+4

y=39

 

Now that we have both of the numbers, we should check our work to ensure it's correct:

 

Does 39+35=74?      Yes it does.

 

Is 39 (the larger of the two numbers) four more than the smallest number (35)?    Yes it is.

Sara can type 90 words in 4 minutes about how many words would you expect her to type in 10 minutes at this rate
Gekata [30.6K]
 first divide 90 by 4 to see how many words per minute

90 ÷ 4 = 22.5

 then multiply 22.5 by 10 to get your answer

so your answer is;

225 words per 10 minutes
