Answer:
a^n=-9+(n-1).5
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=-9
n=?
d=+5
Arithmetic sequence=-9+(n-1)5
=-9+5n-5
Collect like terms
-9-5+5n
-14+5n
So the final answer is
an=-9+(n-1).5
Answer:
The legs are a and b, the hypotenuse is c
Step-by-step explanation:
The legs of a right triangle are the two smaller sides. The hypotenuse is the longest side it is also always opposite of the 90-degree angle. If you need to find the lengths of sides remember the Pythagorean theorem, .
(1.6x + 3.25) + (0.3x + 0.5)
combine like terms
1.6x+.3x +3.25 +.5
Result:
1.9 x + 3.75
