Answer:
D
Step-by-step explanation:
-18 - 36n = -6(3 + 6n).
Use distributive property.
-6(3 + 6n)
-18 + (-36n)
-18 - 36n
-18 - 36n = -18 - 36n
Have a nice day!

Is it's scientific notation.
The quadratic function given to us is:

We are asked to find the vertex form of the function.
The general formula for the vertex form of a quadratic equation is:

In order to write the function in its vertex form, we need to perform a couple of operations on the function.
1. Add and subtract the square of the half of the coefficient of x to the function.
2. Factor out the function with its repeated roots and re-write the equation.
Now, let us solve.
1. Add and subtract the square of the half of the coefficient of x to the function.

2. Factor out the function with its repeated roots and re-write the equation.

Therefore, we can conclude that the Equation and vertex of the equation is:
Answer:
Step-by-step explanation:
2) Let 't' be the temperature
t < 7
Height be 'h'
h >= 42
Cos be represented by 'c'
c >= 125
3) Distributive property: a*(b +c) =(a*b) + (b*c)
2(5a + 3b) + 5a +2b = 2*5a + 2*3b + 5a + 2b
= 10a + 6b + 5a + 2b
= 10a + 5a + 6b + 2b {Combine like terms}
= 15a + 8b
6y + 2(3x + 5) + 2y + 3 = 6y + 2*3x + 2*5 + 2y + 3
= 6y + 6x + 10 + 2y + 3
= 6y + 2y + 10 +3 + 6x
= 8y + 13 + 6x
