3:9 and if you reduce it again, 1:3
If he got a 23 out of 25 just divide 23 by 25 and your answer would be
Answer-92%
Given:-

To find:-
The simplified form.
At first we take conjucate and multiply below and above.
The conjucate is,

So now we multiply. we get,

Now we simplify. so we get,

We know the value of,

Substituting the value -1. we get,

So now we split the term to bring it into the form a+ib. so we get,

So the required solution is,
Answer:

Step-by-step explanation:
we know that
The solution of the inequality is the shaded area below the solid line (the inequality is of the form
)
The y-intercept of the solid line is (0,2)
The x-intercept of the solid line is (-4,0)
The slope of the solid line is

The equation of the solid line is 
therefore
The linear inequality represented by the graph is

Answer:
6 seconds
Step-by-step explanation:
Given
y = - 12x(x - 6)
When the ball hits the ground then height of ball is zero
let y = 0 , that is
- 12x(x - 6) = 0
Equate each factor to zero and solve for x
- 12x = 0 ⇒ x = 0 ← when ball is first kicked
x - 6 = 0 ⇒ x = 6 ← when the ball hits the ground.
The ball hits the ground after 6 seconds
