Answer:
-5
Step-by-step explanation:
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
Answer:
2/3
Step-by-step explanation:
Have a great day
The answer is 95.
First: find the area if the whole rectangle. To do so you would multiply lxw (10x12)
Second: you would find the area of the square. Squares have perfect sides so you would multiply 5x5.
Last: take the sums of both equations. So the it would be 120-25=95.
2 + 2m = 6 equals
m = 2.
First, subtract 2 from both sides. Your problem should look like: 2m = 6 - 2.
Second, simplify 6 - 2 to get 4. Your problem should look like: 2m = 4.
Third, divide both sides by 2. Your problem should look like: m =
Fourth, simplify

to 2. Your problem should look like: m = 2, which is the answer.
