The correct is 44 because you estamate and 48 is close to 44
is there a value to y? if not, this is what I got:
Y^2 + 2y + 3
Start by distributing -5x into x then into -3y. So -5x times x equals -5x^2( -5x squared), then -5 times -3y, equals 15xy so your answer is -5x^2 + 15xy.
Answer:
P = F / A = 40 N / (0.0045 m^2) = 8889 N/m^2
