question 1=30
question 3 =1/20
Step-by-step explanation:
question 1
- 300/2×5
- 300/10
- 300\10 you will take by 0 0
- so the ans is 30/1
- answer is 30
question 2 am not sure
question 3
- it is 20/1
- so the reciprovol of 20/1 is 1/20
- that's all I know for no 2 I will some one. thanks

Step-by-step explanation:
The fourth choice. For example, (x+2)(x-2)>0 we'll get x>2 or x<-2 because whenever you substitute x>2 for example x = 3, the value will be higher than 0 itself.
If we substitute x = 3 (for x>2)
We'll get (3+2)(3-2)>0
5(1)>0
5>0 The statement is true.
If we substitute x = -3 (for x<-2)
We'll get (-3+2)(-3-2)>0
-1(-5)>0
5>0 The statement is true.
We don't say x>2 AND x<-2, In math, we only say x>2 OR x<-2
Step-by-step explanation:
1.Get the equation in the form y = ax2 + bx + c.
2.Calculate -b / 2a. This is the x-coordinate of the vertex.
3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
