Answer:
25x = 75 (Because they are alternate interior angles)
=> x = 75/25
=> x = 3
So, x = 3
Because 25x is equal to 75, the two lines (u and v) are parallel
N/d = 15
d= 4 + 3n
d=n/15
n/15=4+3n
n=60+45n
44n=-60
n=-15/11
-15/11 / d = 15
-15/11 = 15d
d=-1/11
15/11 / 1/11. = 15
Answer:
Step-by-step explanation:
A cube is made up of 6 squares
One square has 4 edges of equal length
The area of one face is Area = s^2
Therefore the surface area is 6 * s^2
The area of this cube is 6 * 5 * 5 = 150 units.
The answer would be:
A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin

Answer: 
Step-by-step explanation:
We know that the standard quadratic equation is ax^2+bx+c=0
Let's compare all the given equation to it and , find discriminant.
1. a=2, b= -7, c=-9
So it has 2 real number solutions.
2. a=1, b=-4, c=4

So it has only 1 real number solution.
3. a=4, b=-3, c=-1

So it has 2 real number solutions.
4. a=1, b=-2, c=-8
So it has 2 real number solutions.
5. a=3, b=5, c=3

Thus it does not has real solutions.
