This is all in one question:
the number of terms in the expression 3x−1 is __
the constant in the expression −2x+1 is __
the coefficient in the expression −x7+3 is __
the factors of the first term in the expression 2x5−8 are __
and __
the second term in the expression 3x−34 is __

1. 3x - 1there are 2 terms...(3x) and (1)
2. the constanta number that stands by itself, with no variable attached.
    -2x + 1...constant is 1
3. coefficienta number that is multiplied by a variable (a letter)
    having trouble understanding this problem...is it -x^7 + 3 ? if so, the coefficient is -1. If it is -7x + 3, the coefficient is -7
4. factors of 2x^5 - 8 ...there are 3 factors, 2, x^5, and -8
5. not sure what ur asking.

Sorry i didn’t know i had

It’s going to be d. 4x^2-4x-19’
