daser333 [38]

Answer:

$\frac{2}{27}$

Step-by-step explanation:

We have given that melissa used 4 cups of sugar to bake 54 cookies.

That means 1 cup of sugar will be used to bake $\frac{54}{4}=\frac{27}{2}$ by unitary method

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be $\frac{27}{2}$

$\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}$

Plzzzzz help me with this

Answer:

We conclude that we must add 4² or 16 to complete the square.

Hence, option C i.e. 16 is the correct answer.

Step-by-step explanation:

We know that the perfect square formula is

(a + b)² = a² + b² + 2ab

Given the equation

$x^2+8x$

Let us add 4² or 16 in the equation

$x^2+8x+4^2$

$x^2+\:2\left(1\right)\left(4\right)x+4^2$

as (a + b)² = a² + b² + 2ab, so

$x^2+8x+4^2=\left(x+4\right)^2$

Therefore, we conclude that we must add 4² or 16 to complete the square.

Hence, option C i.e. 16 is the correct answer.
