Answers:
1, 6, 36, 216: Geometric
12, 4, -4, -12: Arithmetic
1, 2, 8, 64: Neither
-216, -72, -24, -8: Geometric
Explanations:
Arithmetic Sequence: Every number in the sequence is either added or subtracted by the same number. We know that 12, 4, -4, -12 is arithmetic because each number in the sequence is subtracted by 8.
Geometric Sequence: Every number in the sequence is either multiplied or divided by the same number. We know that 1, 6, 36, 216 is geometric because each number in the sequence is multiplied by 6. We also know that -216, -72, -24, -8 is geometric because each number in the sequence is being divided by 3.
Neither: 1, 2, 8, 64 is neither because it is not being added, subtracted, multiplied, or divided by the same number.
I hope this helped!
Answer:
i i honesly dont know im really sorry
Step-by-step explanation:
Follow the order of operations.
First do what is inside the parenthesis
20 + 3(7+4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
Next, do the multiplication
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
Then add
20 + 33 + 5 + 32 = 90

Let’s say the side BC is extended till D
1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
