Answer:
C: 5
Step-by-step explanation:
Here the variable x shows up specifically only once, with coefficient 5:
5x^2 + 3
This actually represents 5x^2 + 0x + 3.
The coefficient of the explicily-given x-term is 5. The other coefficients are 0 and 3.
Answer: x = 5
Step-by-step explanation:To solve this you first need to collect the like terms 6x-2x=7+3. Add those 4x=20. After that you need to divide both sides. Then you will get you solution.
C. 2x+2
Sorry, read the question wrong!
Answer:
21/2 or 10.5
Step-by-step explanation:
Multiply the constants, add up the exponents
4*(-3)*(-7)=84
1+8+3=12
so the result is 84x^12
