Expand (2x - 3y + z)(3x - y+ 4z)6x² - 2xy + 3y² + 4z² + 11xz - 13yz6x² - 11xy + 3y² + 4z² + 11xz - 13yz6x² - 9xy + 3y² + 4z² + 8xz - 12yz6x² - 11xy - 3y² + 4z² + 3xz - 12yz7. Simplify the expression: (3a + b) - (2a - 2b)a + 3b5a + 3b5a - 3ba - 3ba - b8. Simplify; 2x + 5y - 7x + 8y -5x + 3y-5x + 13y5x + 3y9x + 13y9. If xy + 1 = y² and z = 1/x - 1/xy, express z in terms of y1 + y1/ x-y1/ y-11/ y+110. If p varies inversely as qr/ q-r, and p = 5 when q = 7 and r = 2, then p is equal to14(q-r)/ 25qr25(q-r)/ 14qr14(q-r)/ qrq-r/ 14qr11. What number is known as the multiplicative identity?12. 54x²y ÷ 3xy24x22y18x24xy18y13. P varies directly as x and inversely as the square of y.If P = 3 when x = 2 and y = 1, then P can be expressed asP = 2x/3yP = x²/2yP = 3x²/2y²P = 3x/2y²14. Q is jointly proportional to the cube of x and the fourth power of y. If x is halved and y is doubled, then the value of Q isdecreased in the ratio 4 : 1increased in the ratio 1 : 4left unchangedincreased in the ratio 1 : 215. Make y the subject of formula x = a+y/ a-yy = 2a-x/ a+xy = a(x-1)/ x+1y = ax/ a+1y = ax-1/ x+116. 9ab × 6a76a²b56a²b54ab48a²b54a²b17. Simplify the following : 2ab² + ab²c + 3abnone of theseab (2b + bc + 3)2a(b + abc + 3b)6ab(3 + bc + 2)18. What is the algebraic expression to represent y less than twenty Y + 2020 - y20 +Y - 2019.
