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.
No because 22 squared plus 24 squared does not = 26 squared
193+y greater than and equal to 201
Greater than or equal to = ≥
193 + y ≥ 201
193 + y greater than and equal to <span>= </span>193 + y ≥ 201
