y = 3x + 1310x^2 + 78x + 169 = 2510x^2 +78x +144 = 0(5x+24)(2x+6) = 0x = -24/5 or -3y = -7/5 or 16

5/10 * 4/9 = 20/90 = 2/9

1/9

Firstly we need to change each fraction into improper fractions. 7/2- 7/3then we need to give each fraction a common denominator. In this case we will use sixths. 21/6 - 14/6. Ans: 7/6

So to start this question, we must multiply out the bracket as follows:2 x (y+3) = 10(2 x y) + (2 x 3) = 102y + 6 = 10Now we take away 6 from both sides of the equation:2y + 6 = 10 (NOW TAKE AWAY 6)2y = 4...
