You have to substitute the x so since x=7 you have to do 5x7 which is 35 then you add the 2 making 37. Just tell me if you have any questions
Answer: 
Step-by-step explanation:
Given: u and v be are the solutions of 
Let 
is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing to
we get a= 3 , b= 5 and c = 7
Now we have to find
adding and subtracting 2uv in numerator we get
Substituting the values from (i) and (ii) we get
Hence, the value of 
is
D. 15cm, 17cm, 19cm
All values increase by a scale factor of 10.
f(x)= x+10
The answer is zero, so no solution is your answer.
Answer:
531,441·g^6·h^8
Step-by-step explanation:
The operative rule of exponents is ...
(a^b)^c = a^(b·c)
Working from the inside out, according to the order of operations, we get ...
= (9^3·g^3·h^4)^2
= 729^2·g^(3·2)·h^(4·2)
= 531,441·g^6·h^8
