Answer:

a = 5

Step-by-step explanation:

3(a - 4) + 1 = 9 - a Distribute the 3 into a-4

3a - 12 + 1 = 9 - a Combine like terms

[-12 and 1]

3a - 11 = 9 - a Add 11 to both sides to isolate 3a

+11 +11

3a = 20 - a Add a to remove it and have all a

+a +a

4a = 20 Divide by 4 to only have a

/4 /4

a = 5

Identiffy the degree of the polynomail 8x3y2 - 10x + 4x2y2+3

Karo-lina-s [1.5K]

$8x^3y^2-10xy+4x^2y^2+3$
If this is what you mean then the degree of the polynomial would be 3 since 3 is the highest exponent of all the terms.
