Since the triangle is a right angle at BFC, wouldn’t that indicate it’s either 30°, 45°, or 60°? What are the values for the side dimensions?
I don’t see any multiple choice but d3 -343 is factored as (d-7)(d^2+7d+49)
Answer:
15x^3y+6x^2y^2+9xy^3
Step-by-step explanation:
3xy ( 5x^2 +2xy +3y^2)
Distribute the 3xy to all terms in the parentheses
3xy*5x^2+3xy*2xy+3xy*3y^2
15x^3y+6x^2y^2+9xy^3
