Find the area of a regular octogenarian whose side length is 4.7in. and the apothem is 6.5in. a 244.4 in b 122.2 in c 61.1 in d 30.55 in

OCTA = 8.

the perimeter of an OCTAgon is simply the sum of all its sides, we know this one is a regular one, so all sides are equal, if one side is 4.7, then all 8 sides are the same, and therefore its perimeter is simply their sum or just 8*4.7 = 37.6.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
