Answer:
43
Step-by-step explanation:
80-37 = 43
Answer:
A)
Step-by-step explanation:
check that the formula in A works . . .
the 7th term should be 320
a(320) = 5(2)^7-1
= 5(2)^6
= 5(64)
= 320
Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2
now we have a mixed number

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant.

so
Greater
If we get common denominators
1/2=15/30
3/15=6/30
15>6 therefore 1/2>3/15
It can never be a square.
