That would be the same as : 10 × (x + 8)
Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)
29580 + 3440 = 33020. The is about 33,000mi. The answer is d.
Ik almost certain that it would be 216
I'm not quite sure but this is what I got for the answer : 243.17 . I hope this answer helped you, and if I got it wrong I'm really sorry.
