Hello!
To solve for x in algebraic equations, we need to use SADMEP. SADMEP is only used to solve these equation, and our goal is to isolate x. SADMEP is known as: subtraction, addition, division, multiplication, exponents and parentheses.
4x + 8 = 2x + 7 + 2x - 20 (simplify alike terms)
4x + 8 = 4x - 13 (subtract 8 from both sides)
4x = 4x - 21 (subtract 4x from both sides)
0 = -21
This equation has no solutions because 0 is not equal to -21, and is identified as neither because it has no real solutions.
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3
