This questions stated differently so I’m assuming it’s 4?
Answer:
x=3
Step-by-step explanation:
x^2 = 6x - 9
Subtract 6x from each side
x^2 -6x = -9
Add 9 to each side
x^2 -6x+9 = 0
Factor
what 2 numbers multiply to 9 and add to -6
-3*-3 = 9
-3+-3 =-6
(x-3)(x-3) = 0
Using the zero product property
x-3 =0 x-3=0
x=3 with multiplicity 2
The sum of a number is the answer to an equation of a number plus a number you are correct.
Answer:
4
Step-by-step explanation:
Because the formula of distance I'd root under x2 - x1 and y2-y1 and the answer Is 4 units
Answer:
(a)
Step-by-step explanation:
The tangent and the normal at point P are perpendicular.
Given
= 3, then
Given the gradient m of the tangent then the gradient of a line perpendicular to it is
= - 
= - 
→ (a)
