You need to find the area of the the whole rectangle (including white region inside of it). Then subtract the white region from the whole area to get the area of the shaded region.
The area of the whole rectangle is
(9x - 2)(2x + 7)
= 18x^2 + 63x - 4x - 14
= 18x^2 + 59
The area of the white (unshaded) region is
3x(x + 12)
= 3x^2 + 36x
The area of the shaded region will be the area of the whole rectangle minus the area of the white region inside it.
(Area of whole rectangle) - (Area of unshaded region)
= (18x^2 + 59) - (3x^2 + 36x)
= 18x^2 + 59 - 3x^2 - 36x
= 15x^2 - 36x + 59
Answer:
n = 39
Step-by-step explanation:
The base angles are congruent, that is
3n = 117 ( divide both sides by 3 )
n = 39

Answer:
D : This is because there are 8 outcomes and 2 events.
It cannot be C as C does not show true event outcomes on each H or T event.
Step-by-step explanation:
Answer: 62.5% water
100 * 50 / (50 + 30) = 100 times, then you do 50/80 and you get 62.5.
