Answer:
Part a) Option d
Part b) Option a
Step-by-step explanation:
Part a
if we look at the options given and the data available
Option a) x^4+9
Putting x= 2 we get (2^4) + 9 =25
Putting x= 3 we get (3^4) + 9 =90 but f(x) =125 so not correct option
Option b) (4^x)+9
Putting x= 2 we get (4^2) + 9 =25
Putting x= 3 we get (4^3) + 9 =73 but f(x) =125 so not correct option
Option c) x^5
Putting x= 2 we get (2^5) =32 but f(x) =25 so not correct option
Option d) 5^x
Putting x= 2 we get (5^2) =25
Putting x= 3 we get (5^3) =125
Putting x= 4 we get (5^4) =625
So Option d is correct.
Part (b)
3(2)^3x
can be solved as:
=3(2^3)^x
=3(8)^x
So, correct option is a

Answer:
(x-1) (x+4)
Step-by-step explanation:
Factor x^2+3x-4 using the AC method
Hi there!
2(4z - 9 - 7) = 166 - 46
let's make this a little more simpler...
2(4z - 16) = 120
use distributive property.
multiply 2 and 4z , 2 and -16.
8z - 32 = 120
add 32 on both sides to isolate the variable
8z = 152
divide both sides by 8...
z = 19
So your answer is A. 19
Hope this helped!! :)
