Answer:
Step-by-step explanation:
The rule with like bases is that when you multiply them you add their exponents.

Therefore, our final simplification is

3, assuming 2x2 is 2x squared, u will get
4 + 6x3 - 10x2
So 3 terms

Answer:
h = A / ( 1/2 a - 1/2 b)
Step-by-step explanation:
A = ½ ah - ½ bh
Factor out an h
A = h( 1/2 a - 1/2 b)
Divide each side by ( 1/2 a - 1/2 b)
A / ( 1/2 a - 1/2 b) = h ( 1/2 a - 1/2 b)/ ( 1/2 a - 1/2 b)
A / ( 1/2 a - 1/2 b) = h
h = A / ( 1/2 a - 1/2 b)
Answer:
b
Step-by-step explanation:
-2 is the slope so change -2 to 3
