L*w=area
(3x+21)*w=3x^2+33x+84
w=(3x^2+33x+84)/3x+21
(3(x+4)(x+7))/3(x+7)
w=x+4
He will need 527.52 cubic centimeters of wax. You divide the diameter by 2 ten multiply that number by itself to get the circumference. From there you multiply it by 12 then by 4 and there's your answer
the answer is0.0101010101
If you want to solve this i suggest rather dividing or multiplying.
Yes. Both are at a right angle and both have the little tick on line AB and XY, so they must be congruent.
