First think of the form a^2 + 2c + c^2

c in the question is clearly 3.

So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.

So it will be (x^2+3)^2 = 17

So the choice number 3 is the answer.

Hope this helps!

Please it’s an emergency
taurus [48]

Answer: C

Step-by-step explanation:

Okay first set a comparison since the two triangles are similar

x-1/20=x-1+27/3x+8

x-1/20 = x+26/3x+8

cross multiply

20x+520=3x^2+8x-3x-8

3x^2-15x-528=0

3(x^2-5x-176)=0

im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid

x=16, x=-11

it has to be positive so x=16

C

F(x)=3x+10x and g(x)=2x-4, find (f+g)(x)
djyliett [7]

Answer:

15x - 4

Step-by-step explanation:

Add both of the equations together.

f(x) + g(x)

(3x + 10x) + (2x -4)

Then, combine like terms

3x + 2x + 10x = 15x

15x - 4
