Answer:
x² - 6x + 9
Step-by-step explanation:
(a - b)² =a² - 2ab + b²
a = x and b = 3
(x - 3)² = x² - 2*x*3 + 3²
= x² - 6x + 9
Answer:
5
Step-by-step explanation:
2x - 3 = 7
this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7
then you can just solve for x
2x=10
x=5

Answer:
B
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= - 
Given m = -
, then
= -
= 
Since m > 0 then lines LM and No are the 2 possible lines
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = L(- 5, - 3) and (x₂, y₂ ) = M(0, 3)
m =
= 
Hence the required line is LM
