Answer:

A. Add 4 to both sides and subtract 6x from both sides

Step-by-step explanation:

The correct expression is

x^2-3x+16=6x-4

Add 4 to both sides and subtract 6x from both sides

Add 4 to both sides

x^2-3x+16+4=6x-4+4

x^2-3x+20=6x

Subtract 6x from both sides

x^2-3x-6x+20=6x-6x

x^2-9x+20=0

Which of the binomials below is a factor of this trinomial?

KiRa [710]

Answer:

D. x + 4

Step-by-step explanation:

<u>Let's factor the trinomial:</u>

x² + 14x + 40 =
x² + 4x + 10x + 40 =
x(x + 4) + 10(x + 4) =
(x + 4)(x + 10)

x + 4 is between the answer options

Correct option is D.
