Answer:
6x^2 + 11.
Step-by-step explanation:
24x3 - 54x2 + 44x - 99 Re-arranging:
= 24x^3 + 44x - 54x^2 - 99
= 4x(6x^2 + 11) - 9(6x^2 + 11).
Considering that the hallway is rectangular in shape such that its perimeter is calculated by the equation,
P = 2L + 2W
where P is perimeter, L is length, and W is width. Substituting the known values,
10.4 = 2L + 2W
Dividing both sides of the equation by 2,
5.2 = L + W
W = 5.2 - L
Answer:
36π mm²
Step-by-step explanation:
Please, Mark, it's π or pi, not pie.
Formula for the area of a circle: A = πr²
so, if the radius is 6 mm, the area is A =π(6 mm)² = 36π mm²
