Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
It shouldn't be too hard, I've been taking my practice test all day today and yesterday night and I believe i'm going to do good today on my test, just study hard and take the practice test
The value would be $14,000.
The formula we use for this is
A = p(1+r)ˣ, where p is the initial value, r is the percent of depreciation (as a decimal number) and x is the number of years. Note that since it is depreciation, r will be a negative number.
A = 25000(1-0.08)⁷ = 13946.17 ≈ 14000
If the polygons are similar, then the top side is equal to one half of the left side.
Since side (x -1) = 8, then x = 9.
