Answer:

8.9

Step-by-step explanation:

Use Pemdas or Bedmas ( Brackets, Exponents, Division, Multiplication, Addition, Subtraction.

First add 4.5 and 7.6, you get 12.1

Now do the division, 8/2.5 = 3.2

Lastly you subtract, 12.1-3.2 = 8.9

What equation results from completing the square and then factoring? x^2+22x=31 A.(x+22)^2=53 B.(x+22)^2=152 C.(x+11)^2=152 D.(x

Paladinen [302]

Answer:

$\boxed{\mathrm{Option \ C}}$

Step-by-step explanation:

=> $x^2+22x = 31$

=> $(x)^2+2(x)(11) = 31$

Since b = 11 , So $(11)^2$ needs to be added to both sides

Adding $(11)^2$ to both sides

=> $(x)^2+2(x)(11)+(11)^2 = 31+(11)^2$

Completing the square

=> $(x+11)^2 = 31+121$

=> $(x+11)^2 = 152$
