Answer:

D

Step-by-step explanation:

Let's factor x2+8x+16

x2+8x+16

The middle number is 8 and the last number is 16.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 8

Multiply together to get 16

Can you think of the two numbers?

Try 4 and 4:

4+4 = 8

4*4 = 16

Fill in the blanks in

(x+_)(x+_)

with 4 and 4 to get...

(x+4)(x+4)

Answer:

(x+4)(x+4)

Answer:

<h2>D</h2>

Step-by-step explanation:

x^(2)+8x+16=0

(x+4)(x+4)=0

(x+4)^2=0

lets multiply out to check:

x^(2)+8x+16=0,

thus, the answer is (x+4)(x+4), which is option D

Mai's water bottle had 24 ounces in it. After she drank x ounces of water, there were 10 ounces left.
nirvana33 [79]

Answer:

24 - X = 10

Step-by-step explanation:

Given that Mai's water bottle had 24 ounces in it. After she drank x ounces of water, there were 10 ounces left, in order to determine the equation that represents this situation, the following reasoning has to be made:

Since the bottle has 24 ounces of liquid, that is its initial content, from which an amount X is subtracted, after which 10 ounces of water remain. That is, 24 - X = 10.

Thus, this equation is solved in the following way:

24 - X = 10

24 = 10 + X

24 - 10 = X

14 = X
