Answer:
I think the answer would be the very first one.
they all need to have '' ( ) '' in them.
if a number is outside of that, it needs to at least have a letter beside the number
here's an example
Factored form:
2x(x + y)
not factored:
2(x - y)
but for the first one, it's correct from the rest of them.
Answer:
2.52
Step-by-step explanation:
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
I know it’s not right, I think it’s obtuse
Answer:
A. (2i)(8) = d. 16i
B. 16i³ = b. -16i
C. (2i)⁴ = a. 16
D. (2i)(8i) = c. -16
Step-by-step explanation:
A. Multiply 2i by 8 to get 16i, which corresponds to d.
B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.
C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.
D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.
