Answer:
A.
Step-by-step explanation:
The a^3 would cancel out, currently leaving just b^5 on the top and ab on the bottom. The b would also cancel out, finally leaving just b^4/a. Therefore A is the answer equivalent to the original expression.
Answer:

Step-by-step explanation:
Given
4
- 10
+ 7
( add the coefficients of the terms )
= (4 - 10 + 7) 
= 1
= 
The equation of a circle is
(x-h)² + (y-k)² = r²
for center (h, k) and radius r. Of course, the radius can be computed by putting the point in the equation.
(x-2)² + (y-3)² = (-1-2)² + (1-3)² = 9+4 = 13
The standard equation of the circle is (x-2)² + (y-3)² = 13.
There ya go, the graphing
you know dam well what 34+35 is...
70-1...
68+1....
