Answer:

Step-by-step explanation:
Degree is the highest exponent on the variable in a polynomial.
A leading coefficient is the first terms coefficient when the polynomial is written in standard form.
To write this polynomial, write
as your first term. Its leading coefficient is -4 and it has a degree of 3. Then add whatever terms after it being sure to not add any more with exponent 3 or higher.

Answer:
x = 6
Step-by-step explanation:
first you would put them equal because they have the same angle: 9x + 10 = 2x + 52
subtract 10 from both sides: 9x = 2x + 42
subtract 2x from both sides: 7x = 42
divide by 7 on both sides x = 6
hope this helps! :)
