Step-by-step explanation:
![sum = \frac{n}{2} [2a + (n - 1)d] \\ \\ sum = \frac{50}{2} [(2 \times 1) + (50 - 1) \times 1] \\ \\ sum = 25(51) \\ sum = 1275](https://tex.z-dn.net/?f=sum%20%3D%20%20%5Cfrac%7Bn%7D%7B2%7D%20%5B2a%20%2B%20%28n%20-%201%29d%5D%20%5C%5C%20%20%5C%5C%20sum%20%3D%20%20%5Cfrac%7B50%7D%7B2%7D%20%5B%282%20%5Ctimes%201%29%20%2B%20%2850%20-%201%29%20%5Ctimes%201%5D%20%5C%5C%20%20%5C%5C%20sum%20%3D%2025%2851%29%20%5C%5C%20sum%20%3D%201275)

Because when multiplying by a negative with a negative you will get a positive and multiplying a negative with a positive will get you a negative
Answer:
1/5? 0.2?
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>The figure consist of:</u>
- 1. A rectangle with sides 10 cm and 17 cm
- 2. A quarter circle
<u>The perimeter is:</u>
- P = 1/4C + 2*10 + 17 + (17 - 8) + 8
- P = 1/4*2*3.14*8 + 54 = 66.56 cm
The arithmetic formula is expressed as an = a1 + d *(n-1)where n is an integer. Substituting from the given a1 = -12 and a27 = 66, 66 = -12 + d *(27-1). hence , d is equal to 3. a42 thus using the formula is equal to 111. The final answer to this problem is 111.
