A binomial squared is written like

x^2+2ax+a^2

So, we have 2a=6 \iff a=3

So, we want to complete the square (x+3)^2 = x^2+6x+9

We can add and subtract 9 to write

x^2+6x = x^2+6x+(9-9) = (x^2+6x+9)-9 = (x+3)^2-9

For the functions f(x) = 2x − 6 and g(x) = 5x + 1, which composition produces the greatest output? A. Both compositions produce
o-na [289]
F(g(x)) = 2(5x+1)-6 = 10x+2-6 = 10x-4

g(f(x)) = 5(2x-6)+1 = 10x-30+1 = 10-29

10x-4>10-29 because from f(g(x)) you subtract less quantity. 
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.

Is -pi a rational or irrational number
Lyrx [107]

Answer:

I believe that it is a irrational number.

Step-by-step explanation:

An irrational number is a number that cannot be written as a fraction with a num and denom that aren't equal to 0. These cannot be expressed as repeating decimals. -pi has all these traits, therefore it's irrational.

F(x) = 2x2 − 30, find f(4).
Leviafan [203]

Answer:

F(4)= 2

Step-by-step explanation:

F(x) = 2x^2 − 30, find f(4).

F(4)= (2)(4)^2 - 30

F(4)= (2)(16) - 30

F(4)= 32 - 30

F(4)= 2

Mrs porcelli’s classroom bulletin board is 2/1/4 feet long. Ms Smith’s bulletin board is 3 times as long Mrs porcelli’s.How long
yuradex [85]

Answer:

6.75 or 6 3/4

Step-by-step explanation:

First take the whole number and multiply that by 3.

2*3=6

Now, take the fraction and multiply that times 3.

1/4 as a decimal is 0.25. You can ignore the decimal point right now, but you have to remember it is there later.

So, whithout the decimal point, 25*3= 75.

Now, you add the decimal. The 75 is now 0.75, with the decimal.

Add the whole number and the decimal, and you have your answer!

6+0.75=6.75. As a fraction this is 6 3/4
