4x^2 - 36 = 0
4x^2 = 36
x^2 = 9
x = 3 or -3
the answer is C

plus 20 or positive
Step-by-step explanation:
-60+80= 20
positive
Answer: 1/3
<u>Divide</u>
30/90÷30/30=1/3
Since we are simplifying fractions we divide the numerator and the denominator by a number the fraction can go into.
We could use 10 then divide by 3. You can also just divide by 30 and get the answer.
Let's try dividing by 10 then 3!
30/90÷10/10=3/9
3/9÷3/3=1/3
As you can see we still get 1/3 when we divide by 3. Even tho you have to divide twice you still get 1/3. That's all that matters.
Because AC is a diameter we can find the 180/3 = x
giving us the x= 60
Then that arc AB = 120
Answer:
X = 25
Step-by-step explanation:
We can calculate the value of x using Euclidean theorem
15^2 = 9 × x
225 = 9x divide both sides by 9
25 = x
