Answer:

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Step-by-step explanation:

The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;

Actual cost - (Percentage discount) Actual cost = Total cost

The correct options are;

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Jackson used the process of completing the square to solve the equation 2x2−12x=−6.

Nikolay [14]

Answer:

$x=3-\sqrt{6},x=3+\sqrt{6}$

Step-by-step explanation:

we are given equation as

$2x^2-12x=-6$

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

$2(x^2-6x)=-3\times 2$

step-2:

Simplify it

$x^2-6x=-3$

step-3:

Add both sides 3^2

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

now, we can complete square

$(x-3)^2=6$

step-4:

Take sqrt both sides

$(x-3)=-\sqrt{6},(x-3)=\sqrt{6}$

step-5:

Add both sides by 3

we get

$x=3-\sqrt{6},x=3+\sqrt{6}$
