2x12=
her answer is incorrect
If lines are parallel, slopes are equal
If lines are perpendicular, the product of the slopes is -1.
The formula to find the slope is
1)
Here P (a, b) & Q(c,d)
Slope of PQ
Also P'(-b, a) & Q'(-d,c)
Solpe of P'Q'
Now slope of PQ × Slope of P'Q'
As the product of slopes = -1.
PQ & P'Q' are perpendicular to each other.
2)
P(w,v), Q(x,z)
Slope of PQ
P'(w+a, v+b), Q' (x+a, z+b)
Slope of P'Q'
Hence slope of PQ = Slope of P'Q'
Hence PQ is parallel to P'Q'
Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.
Answer:
(4x - 1)(3x - 1).
Step-by-step explanation:
I think you mean 12x^2 - 7x + 1
= 12x^2 - 4x - 3x + 1
= 4x(3x - 1) -- 1(3x - 1)
= (4x - 1)(3x - 1).
