Answer:
Step-by-step explanation:
(x + 2)² = (x - 1)(x + 14)
x² + 4x + 4 = x² + 13x - 14
-9x = -18
x = 2
Answer:
Option (a) is correct.
is a perfect cube.
Step-by-step explanation:
Given : Some Monomial
We have to choose out of given monomial that is a perfect cube.
Perfect cubes are numbers that can be written as 
So, consider
, we know 1 can be written as 
Thus,
can be written as 
Thus, Option (a) is correct.
Equality d is true, the others aren't.
Answer:
y =
x - 2
Step-by-step explanation:
Given parameters:
Coordinates = p(4,0)
Equation of the line -x+2y=12
Solution:
A line parallel to the given line will have the same slope as it is;
-x+2y=12
2y = x + 12
y =
x + 
Since this conforms to y = mx + c where;
x and y are the coordinates
m is the slope
c is the intercept
Our slope is 
The equation of the line is
y = mx + c
let us find c;
c = y - mx
c = 0 - (
x 4)
c = -2
Now the equation of the line parallel to the line given is;
y =
x - 2
Answer:
Below.
Step-by-step explanation:
Angle 1 = (3/(3+4+5) * 180 = 3/12 * 180
= 45 degrees.
Angle 2 = 4/12 * 180 = 60 degrees.
Angle 3 = 5/12 * 180 = 75 degrees.
