The answer of this question is b
Answer:
The answer is 448 seconds
Step-by-step explanation:
I guess this is a geometric series:
a6 = a1 * r^5 so
a1 = 0.03125 / 0.5^5
= 1 answer
Here you go :) AA (Angle-Angle) If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
Easy, showing work,
using the method FOIL (First,Outer,Inner, Last)
Take, (x+3)(x+5) and multiply,
First,
x*x=
![x^{2}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20)
Outer,
x*5=5x
Inner,
3*x=3x
Last,
3*5=15
Add the terms together,
![x^{2}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20)
+8x+15 (
![x^{2}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20)
+5x+3x+15)
Thus, your answer.
