Answer: i think it’s option D i might be wrong
Step-by-step explanation: i think it’s option D i might be wrong
The first Choice is correct
Answer:
see below
Step-by-step explanation:
The applicable rules of exponents are ...
- (a^b)(a^c) = a^(b+c)
- a^(-b) = 1/a^b
Using these to simplify your expression, you get ...
a^2+b^2=c^2
where c=25 m. and a=2b-10 m.
substitute
(2b-10)^2+b^2=25^2
4b^2-40b+100+b^2=625
5b^2-40b+100=625
divide both sides by 5
b^2-8b+20=125
subtract 20 from both sides
b^2-8b=105
complete the square
take half of 8 and square it=16
