數學：

7 (a)

(-5)(3w + 2k)

= -15w - 10k



7 (b)

2p(p2 - 4p + 5)

= 2p3 - 8p2 + 10p



7(c)

( 3a + 4)(a – 3)

= 3a2 + 4a - 9a - 12

= 3a2 - 5a -12



8 (a)

x + 5 = 11

x = 11 - 5

x = 6



8 (b)

2 - y = -6

y = 2 + 6

y = 8



8 (c)

5a - 4 = 11 + 10a

10a - 5a = -11 - 4

5a = -15

a = -3



8 (d)

7(t - 3) = 2(t + 2)

7t - 21 = 2t + 4

7t - 2t = 21 + 4

5t = 25

t = 5



9 (a)

項：

2a2, -3



c3 + 2ac3

----------- , a3 , 6

1


(10)

把 n = 1/3 代入 m = 2/3 (n-2)，變成：

m = 2/3 (1/3 - 2)

m = 2/9 - 4/3

m = -10/9



乙部

1.

若面積是 Acm2，則

A = [(2ycm + 6ycm) x (y +1)cm] / 2

A = [8ycm x (y + 1)cm] /2

A = [(8y2 + 8)/2 ]cm2

A = (4y2 + 4)cm2



2.

($72 - $3a) / 2 = $15

72 - 3a = 30

3a = 42

a = 14



5.

[(x + 1) + 5] 2 m > 15 m

(x + 6) 2 m > 15 m

2x + 12 > 15

2x > 3

x > 1.5



6 (a)

3x



6 (b)

3x / 2

= 1.5x

真係睇唔到wo~~
