Answer: A or B but really A

Step-by-step explanation:

Answer: A and B.

Step-by-step explanation:

When you multiply 12 by 12, you get 144, and when you multiply 13 by 13, you get 169.

This works with negatives too because a negative times a negative is a positive.

Round to the nearest hundredth 26.9816

VARVARA [1.3K]

$\huge{\boxed{26.98}}$

The hundredths place is the second place after the decimal point. In this case, it is $8$ .

We can round it by looking at the next place to the right, which is a $1$ . $1$ is less than $5$ , so we can just cut off everything after the hundredths place. This leaves an answer of $\boxed{26.98}$ .

Answer:

C. 16

Step-by-step explanation:

First of all, these two angles are corresponding angles, which means that they equal each other. So, the equation here would be: 2x+18= 4x-14.

Step 1- Move the variables to one side.

2x+18= 4x-14

-2x -2x

18= 2x-14

Step 2- Add 14 to both sides of the equation.

18= 2x-14

+14 +14

32= 2x

Step 3- Divide 2 to both sides of the equation to isolate the variable.

32= 2x

2 2

x= 16
