Answer:

Step-by-step explanation:
The side-splitter theorem states that a line parallel to a side of a triangle that intersects the other two sides of said triangle divides those two sides proportionally.
Therefore, we have the proportion:

Cross-multiplying, we get:

Answer:
A share of ABC stock was worth $60 in 2005 and only worth $45 in 2010. ... diftolence b. Write an exponential function that ...
Part B. f(x) = 90 + 0.11x
f(300) = 90 + 0.11(300) = 90 + 33 = $123
f(300) represents the total cost, in dollars, for renting a car for a week and driving it for 300 miles.
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
