Answer:
Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.
However in working out, here is what I did.
x^2 + x - 30 = 12 (+30)
= x^2 + x = 42
Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.
Answer:
B. -1/8
Step-by-step explanation:
Using the terms given in the sequence:
4, -2, 1, -1/2, 1/4
we can find the pattern by dividing since it is a geometric seqence:
-2/4 = -1/2
1/-2 = -1/2
-1/2 ÷ 1 = -1/2
So, each term is multiplied by -1/2 to get the next term in the sequence:

Answer:
5.83
Step-by-step explanation:
Use the Pythagorean theorem:
3^2+5^2 = c^2
34 = c^2
sqrt34 = c
5.83 = c
If your number is smaller than the actual number, you underestimated. If it is larger, you overestimated. Please mark Brainliest!!!
