Answer:
Question unclear.
If the question was about the perimeter of the rectangle, it is calculated as:
= (Length * 2) + (Height * 2)
= (11 * 2) + (6 * 2)
= 22 + 12
= 34 cm
If the question was bout Area, the area is:
= Length * width
= 11 * 6
= 66 cm²

Answer:

Step-by-step explanation:
Hello,
f(x)=5x-12
we need to find x so that

<u>so first of all we can write</u>

and f(x+1) = 5(x+1) - 12 = 5x + 5 -12 = 5x - 7
then solving

is equivalent to

Hope this helps
If -5 is a zero then f(x) is divisible by (x + 5)
the quotient when F*x) is divided by x + 5 is :-
3x^2 - 10x + 3
this factors to
(3x - 1)(x - 3)
so the answer is (x + 5)(3x - 1)(x - 3)
Cot (210) = √3
cot(-150°) = <span>√3
cot(30°) = </span><span>√3
-cot(30°) = -</span><span>√3 .....................this is not equal to cot (210°)
-cot(-30°) = </span>√3
