One piece is 3 ft long and the other is 23 ft long
Answer:
x = 21
Step-by-step explanation:
3x - 71 = 2x - 50
3x - 2x = -50 + 71
x = 21
Check:
3(21) - 71 = 2(21) - 50
63 - 71 = 42 - 50
-8 = -8

Hello from MrBillDoesMath!
Answer:
The second choice
Discussion:
The first choice is not a polynomial because it contains sqrt(x)
The third choice is not a polynomial because it contains (1/x)
The fourth choice is not a polynomial because it contains x in the exponent (ie. 5^x)
Thank you,
MrB
To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:
2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2
The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.
