Answer:  Choice A

y = -3(x+2)^2 + 10

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

Work Shown:

y = -3x^2-12x-2 is in the form y = ax^2+bx+c with

a = -3

b = -12

c = -2

The x coordinate of the vertex is

h = -b/(2a)

h = -(-12)/(2*(-3))

h = 12/(-6)

h = -2

We'll plug this into the original equation to find the corresponding y coordinate of the vertex.

y = -3x^2-12x-2

y = -3(-2)^2-12(-2)-2

y = 10

So k = 10 is the y coordinate of the vertex.

Overall, the vertex is (h,k) = (-2,10)

Meaning that we go from this general vertex form

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

to this

y = -3(x - (-2))^2 + 10

y = -3(x+2)^2 + 10

Answer:

24a^4 +36a^3+12a^2

Step-by-step explanation:

area = height × width

area= 4a^2(6a^2+9a+3)

area = 24a^4 +36a^3+12a^2

I need step by step explanation for this!!

Hello! :)

Answer:

\huge\boxed{751}

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.
