Answer:
a = 36 , b = 6
Step-by-step explanation:
expand the right side using FOIL and compare coefficients with like terms on left side.
(x - b)²
= x² - 2bx + b² , compare to x² - 12x + a , then
- 2b = - 12 ( divide both sides by - 2 )
b = 6
and a = b² = 6² = 36
The answer to your Q is 4
Well one dm= 10 cm
12-10= 2 cm
Parallel lines share the same slope, so the slope of the parallel line in this case must be 
.
Point-slope form is 
, where 
is the slope and 
is any known point on the line.
Plug in the values. 
Simplify and distribute. 
Subtract 1 from both sides. 
Answer:
9/2
Step-by-step explanation:
A Rational Number can be made by dividing two integers. (An integer is a number with no fractional part.) So therefore, 9/2 is a rational number
