Answer:
P = 10x³ + 4x² + 8x + 6
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L+W) = 2((x³ +2x² -6x +12) +(4x³ +10x -9))
= 2(5x³ +2x² +4x +3) . . . . collect terms inside parentheses
P = 10x³ +4x² +8x +6
This is an inscribed quadrilateral. The opposite angles are supplementary. They add to 180 degrees.
angleB + angleD = 180
93 + x+30 = 180
x+123 = 180
x+123 = 180-123
x = 57

Answer:
210 degrees
Step-by-step explanation:
Convert the problem from radians to degrees using the ratio 180/ and it will give you 210.
I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.
