By setting up proportions and cross multiplying, the height would be 990.8.
I estimated the answer to be 18,000
Without estimation the answer would be 18,109
Answer:
a = 1.5
b = 1.75
Step-by-step explanation:
First, we need to solve 
and replace the result in the initial equation as:
Then, this equality apply only if the coefficient of 
is equal in both sides and the constant is equal in both sides.
It means that we have two equations:
So, using the first equation and solving for a, we get:
Finally, replacing the value of a in the second equation and solving for b, we get:
Answer:
(n + 1)(3n + 7)
Step-by-step explanation:
3n² + 10n + 7
Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.
product = 3 × 7 = 21 and sum = + 10
The factors are + 3 and + 7
Use these factors to split the n- term
3n² + 3n + 7n + 7 ( factor the first/second and third/fourth terms )
3n(n + 1) + 7(n + 1) ← factor out (n + 1) from each term
= (n + 1)(3n + 7) ← in factored form
