natali 33 [55]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

let's solve for x ~

$37x = 9x + 4$

$37x - 9x = 4$

$28x = 4$

$x = \dfrac{4}{28}$

$x = \dfrac{1}{7}$

What number should be added to both sides of the equation to complete the square? x2 – 6x = 5

choli [55]

Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)
