First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>

Answer:
B. 12 × 18 = n
Step-by-step explanation:
1. <u>the product of 12 and 18</u> is equal to a number.
Product means to multiply, so, you multiply 12 and 18
2. the product of 12 and 18 is <u>equal to a number.</u>
lets say the letter to represent the number is x
so the product of 12 and 18 (12 × 18) will equal x
then put it in order
1. 12 × 18
2. = x
3. 12 × 18 = x
