Answer: -31 l guess
explanation:The sum of two consecutive odd numbers is divisible by 4. An even number is divisible by 2, so it can be represented by 2n, where n is an integer. If we add 1 to an even number, then it will be odd. Therefore, an odd number can be represented as 2n + 1.

Answer:
35
Step-by-step explanation:
i'm either really confused or there's a lot of weird typos in this
assuming there's just a lot of weird typos, this is how you would solve it:
1. plug in -1 for a and 3 for b

2. multiply 3 by -1

3. multiply 3 by -3

4. add 50 to -9

5. subtract 6 from 41

Answer:
20
Step-by-step explanation:
The question tells us that line a is parallel to line b (even if they don't seem to be in the image).
∠8 = ∠4 and ∠5 = ∠1 since line t crosses the parallel lines.
We are given ∠4 = 3x and ∠5 = 6x.
Since we know ∠8 = ∠4 , we can then say
∠8 = 3x and ∠5 = 6x
Since ∠8 and ∠5 are complementary and combined they form a flat angle of 180 degrees, we can say:
3x + 6x = 180
9x = 180
x = 20
Answer:
320.31 in²
Step-by-step explanation:
The area of a circle can be computed from ...
A = (π/4)d²
Filling in the numbers and doing the arithmetic, we get ...
A = (3.14/4)(20.2 in)² ≈ 320.31 in²
