PLEASE HELP ME WITH THESE SET OF QUESTIONS! WORTH 15 POINTS IF YOU SOLVE IT CORRECTLY!!! 1.)Which statements are true? 1.) Choose all answers that are correct. –5b^4(7b^2 + 4) = –35b^8 – 20b^3 –4y^5(3y^3 + 2) = –12y^8 – 8y^5 –3c^6(4c^3 + 5) = –12c^9 – 15c^6 –6x^3(5x^3 + 3) = –30x^9 – 18x^3 2.) Which expression is equal to (x – 3)(2x^2 + 3x – 4)? 2x^3 – 3x^2 + 13x – 12 5x^2 – 13x + 12 5x^2 + 13x – 12 2x^3 – 3x^2 – 13x + 12 6b3 + 9b2 – 12b 3.) Which represents the polynomial in factored form? 3b^2(3b^2 + 6b – 9) 3b^3(2b^2 + 3b – 4) 3b(2b^2 + 3b – 4) 3b(2b^2 + 9b^2 – 12b)
