Answer:
0.44444444 or 4/9
Step-by-step explanation:
Since we know the value of
, we can rewrite the equation replacing the variables.

Now solve. While solving, remember the order of operations.
or 
Answer:
a=-1
Step-by-step explanation:
a(n) = -6+3(n-1)
a(n) = -6+3n-3
a(n) -n=-6+3n-n-3
a=-6+3-3
+3 +3
a3=-3
---- ----
3 3
a=-1
Answer:
AB = 25
Step-by-step explanation:
First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC =
, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle
times larger than the corresponding side on the small triangle. That means AB is
times larger than BC as well. So multiply BC by
get us the answer.
You multiply and add like terms, depending on the equation that you have
∛(2x + 5) - 3 = 0
Add 3 to both sides
∛(2x + 5) = 3
Cube both sides
2x + 5 = 27
Subtract 5 from both sides
2x = 22
Divide both sides by 2
x=11
There's your answer. Have an awesome day! :)
