Answer:
false a = -3
Step-by-step explanation:
7v^2 + 2v^3 -7v - (5v^3 -4v^2 +10v)
7v^2 + 2v^3 -7v - 5v^3 +4v^2 -10v
-3v^3 + 11v^2 -17v

Answer:
I think this is a pretty good question of law of indices
Step-by-step explanation:
Given that 

a) express n in terms of p and q , 
b) hence if p = 1 and q = 2 find the value of n
Solution to part a)

Simplify the equation and how do we do that? As we can see that 9 can also be written as 3^2 and 27 can be written as 3^3 we can rewrite the following equation like this, 

now we multiply p with 2 and 
multiply q with 3 respectively,

now since the bases are same and are multiplying the exponents will add themselves like this, in this equation the number 3 is the base 

now since the bases on the left hand side and on the right hand side are equal the exponents will also be equal so now,

hence n is expressed in terms of p and q
Solution to part b)
if p = 1 and q = 2 we plug in these values in the above equation we found for n
n = 2p + 3q
n = 2(1) + 3(2)
n = 2 + 6
n = 7
 
        
             
        
        
        
Hello there!
To solve this equation, do 1232 ÷ 28 = 44 
(To check if that is correct, do 44 × 28 which = 1232)
So there you go! The answer to your question is C. 44 ft per year
Hope I helped!
