Answer:

Step-by-step explanation:

Use distributive property: a*(b+c) = (a*b) + (a*c)

-4a*(2a + 1) = -4a*2a + 1*(-4a)

                  = -8a² - 4a

2a + 1 - 4a(2a + 1) + 4a = 2a + 1 - 8a² - 4a + 4a

                                    = 2a + 1 - 8a²

PLEASE HELP. !!!!!!!!!

<h3>Answer:    (x+7)^2 + (y+2)^2 = 4</h3>

===========================================================

Explanation:

The center is at (h,k) = (-7,-2)

h = -7

k = -2

The radius is r = 2 units

Plug these three pieces of info into the template below and simplify

(x-h)^2 + (y-k)^2 = r^2

(x-(-7))^2 + (y-(-2))^2 = (2)^2

(x+7)^2 + (y+2)^2 = 4

You can use a tool like Desmos or GeoGebra to confirm the answer.

Anybody know which once it is??
Aleks04 [339]

Answer:

It is the 3rd choice

Step-by-step explanation:

The ratio of red candies to blue is 5:3 as you probably learned, the ratio ':' sign also means the fraction division sign. So we can also write this as 5/3. Lastly how we READ a ratio is; something TO something. In this case if we were to read 5:3 we would say " Five to Three" since there is no choice spelling out the numerals we can just say " 5 to 3". All of these ways are given in the 3rd answer choice.

I hope this helps!
