Answer:
2x²+3x-54
Step-by-step explanation:
(2x-9)(x+6)
=x(2x-9)+6(2x-9)
=2x²-9x+12x-54
=2x²+3x-54
Answer:
32
Step-by-step explanation:
32 × 1 = 32

Answer:
f(0,0)=ln19
Step-by-step explanation:
is given as continuous function, so there exist and it is equal to f(0,0).
Put x=rcosA annd y=rsinA
we know that , so we have that
So f(0,0)=ln19.
Answer:
s = 6
Step-by-step explanation:
-7 = s + (-13)
- 7 = s - 13
-7 + 13 = s
6 = s
Answer:
i) 7x + 8 = -90
<=> 7x = -98
<=> x = -98/7
<=> x = -14
ii) 5y - 4 = 2y - 25
<=>3y = -21
<=> y = -21/3
<=> y = -7
iii) 4(p + 3) = 36
<=> p + 3 = 36/4
<=> p + 3 = 9
<=> p = 9 - 3
<=> p = 6
iv) 2 (4f + 3) = 3 (2f + 6)
<=> 8f + 6 = 6f + 18
<=> 2f = 12
<=> f = 12/2
<=> f =6
Hope this helps!
