Answer 1

Answer:

32. a) 64

Step-by-step explanation:

3 ^x+1 = 9 ^ x-2

= 3 ^ x+1 = 3^ 2x-4

by comparing powers -

x+1 = 2x -4

Thus, x = 5

Now,

2^ 1+x

= 64

Answer 2

Answer:

31.Option D

32.Option A

Step-by-step explanation:

31.Given that:-

3a-2b+c=0

3a+c=2b

On squaring both sides,then

(3a+c)²=(2b)²

We know that (a+b)²=a²+2ab+b²

Here, a=3a and b=c

=>(3a)²+2(3a)(c)+c²=4b²

=>9a²+6ac+c²=4b²

=>9a²-4b²+c²+6ac=0
