The best and most correct answer among the choices provided by your question is the second choice or letter B. 12

Substituting b = 12:

x^2 + 12x + 36 = (x + 6) ( X + 6) ; therefore, a perfect square.

Answer:

The correct option is B.

Step-by-step explanation:

The given polynomial is

p(x)=x^2+bx+36                .... (1)

A perfect square trinomial is

(x+y)^2=x^2+2xy+y^2          .... (2)

On comparing (1) and (2), we get

b=2y             .... (3)

y^2=36

Taking square root both the sides.

y=6

Put y=6 in equation (3).

b=2(6)=12

The value of b is 12, therefore the correct option is B.

can someone please help I don’t get it and I just want answers I have been trying to solve this for 1 hour now
dusya [7]

Answer:

1. y + 10 - 3/2y = -y/2 + 10

2. 2r+ 7r-r - 9 = 8r - 9

3.  7 + 4p-5+p+2q = 2 + 5p + 2q

Step-by-step explanation:

basically you can add terms that have the same variable

integers can be added together, Xs can be added, Zs, Ys, As, Bs, Cs, you get the point

1. y + 10 - 3/2y = -y/2 + 10

2. 2r+ 7r-r - 9 = 8r - 9

3.  7 + 4p-5+p+2q = 2 + 5p + 2q (do not add different variables p and q ) together

try 4-6 on your own to get this skill down, if you need help with those just let me know

SOMEONE HELP! PLEASE! read the attached files
Trava [24]

Answer: 43 squared units

Explanation:

So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area

So basically since this one is a open polygon you can just count the inside of the poly using the squares

X-2=3(x-4) what is the solution
Vladimir [108]
First distribute 3 to (x-4). that gives you 3x-12. Now your equation is x-2=3x-12. Now you subtract x from 3x. now you're equation is -2=2x-12. then add 12 to the left. You're final answer is 10.
