The rule for this one is called the difference of squares
A^2 - b ^2 = (a+b)(a-b)
Using this rule
N^2 - 62 = (n+ sqrt(62)) (n - sqrt(62))
The solution for this one is to make the statement = 0
0 = (n+ sqrt(62)) (n - sqrt(62))
N can either be +- sqrt(62)
Answer:
5 : 1
Step-by-step explanation:
From your second-grade memorization of multiplication tables, you recognize that 15 = 3×5, so you know 3 is a factor of both numbers in the ratio. To reduce the ratio to simplest form, you divide out all common factors:
15 : 3 = (15/3) : (3/3) = 5 : 1
Answer:
607,261
Step-by-step explanation:
Answer:
The slope is 2/3
Step-by-step explanation:
The line crosses through the blue grid lines leaving gaps on each. Find two points which cross at an intersection such as (0,30) and (30,50). Find the slope by substituting these points into the slope formula:
Answer:
81
Step-by-step explanation:
g(x) = x^4 put f(x) in for x in g(x)
g(f(x)) = (f(x))^4 Substitute the value for f(x) which is (-2x - 5) put - 4 in for the x in f(x)
g(f(x) = (-2x - 5)^4
g(f(x)) = (- 2*(- 4) - 5)^4 Combine
g(f(x)) = (8 - 5)^4 Subtract
g(-4) = (3)^4 Raise 3 to the 4th power
g(-4) = 81 Answer.
