25% = 25/100 = 0.25

9*0.25 = 2.25.

You save $2.25 with the discount.

Answer:

$2.25.

Step by step explanation:

We have been given that the cake store is having a 25% off sale on all of its cakes.

To find our savings with the discount we will find 25% of $9 (regular cost of cake).

\text{Savings with the discount}=9\times\frac{25}{100}

\text{Savings with the discount}=9\times\frac{1}{4}

\text{Savings with the discount}=\frac{9}{4}=2.25

Therefore, we will save $2.25 with the given discount.

Which of the following is an equivalent equation obtained by completing the square of the expression below? x^2+6x−8=0 A (x+3)^2
valentina_108 [34]

Answer:

Solving the equation x^2+6x-8=0 by completing the square method we get \mathbf{(x+3)^2=17}

Option B is correct option.

Step-by-step explanation:

We need to solve the equation x^2+6x-8=0 by completing the square method.

For completing the square method: we need to follow: a^2+2ab+b^2=(a+b)^2

We are given:

x^2+6x-8=0

Solving by completing the square

x^2+2(x)(?)+(?)^2-8=0

We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.

So, adding and subtracting (3)^2

x^2+2(x)(3)+(3)^2-8-(3)^2=0\\(x+3)^2-8-9=0\\(x+3)^2-17=0\\(x+3)^2=17

So, solving the equation x^2+6x-8=0 by completing the square method we get \mathbf{(x+3)^2=17}

Option B is correct option.
