Answer:
C.
Step-by-step explanation: im pretty sure because if you look at Ed its 5 and then if you add the same sides twice its 10 hopefully im right
I think the answer is A because it I'm right it did double the size.
Answer:
The answer is 
±
in exact form or 
, 
in decimal form.
Step-by-step explanation:
To solve this problem, start by moving all terms to the left side of the equation and simplify. Simplify the equation by subtracting 12 from both sides of the equation and squaring 
, which will look like 
. Next, simplify the equation again, which will look like 
.
Then, use the quadratic formula to find the solutions. The quadratic formula looks like
.
For this problem, the quadratic variables are as follows:
The next step is to substitute the values , , and into the quadratic formula and solve. The quadratic formula will look like 
. To simplify the equation, start by simplifying the numerator, which will look like 
. Then, multiply 2 by 1 and simplify the equation, which will look like 
. The final answer is ± in exact form. In decimal form, the final answer is , .
Sometimes it helps to put a number line in front of you. If one number is to the left of the other number on the number line, it's a lower number. If one number is to the right of the other number on the number line, it is greater.
-5 -4 -3 -2 -1 0 1 2 3 4 5
4 is a solution of x<-5
FALSE: 4 is not greater than -5
-3 is a solution of y>-2
FALSE: -3 is not greater than -2
y≤3 includes 3 as a possible solution
TRUE: 3 is less than OR EQUAL to 3
Hope this helps! :)
