A - 200.96 sq inches
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>
its a b and c they all equal 45
