Answer:
a
Step-by-step explanation:
The answer is 5 you’re welcome
36x^2-49
this closely matches the binomial formula of (a+b)*(a-b)=a^2-b^2
so we know:
a^2=36x^2
a=6x
b^2=49
b=7
so (a+b)*(a-b)=(6x+7)*(6x-7)=36x^2-49
Answer:
48/37 + (8/37)i.
Step-by-step explanation:
8 / (6 - i)
We multiply top and bottom of the fraction by the conjugate of 6 - i , which is 6 + [email protected]
= 8*(6 + i) / (6 - i)(6 + i)
= 48 + 8i / (36 + 6i - 6i - i^2)
= 48 + 8i / (36 - (-1))
= 48 + 8i / 37
= 48/37 + (8/37)i.
