Answer:
4c^4
Step-by-step explanation:
area of triangle = bh/2
area = 2c^3 * 4c/2
area = 8c^4/2
area = 4c^4
B/3a
a/b*b/2a= ab/2ab or 1/a
1/a*b/2a=b/3a
Option b is the answer to your question
I would said it is Annual means yearly so you need to get the rate each year
156/5=31.2
31.2 Dollars every year
31.2/520=.06
.06*100=6% interest rate every year
So solve for x
|x-72.5|=4
the || makes the inside positive so it could be positivie and negative so
x-72.5=4 and x-72.5=-4
solve for x in both situations
x-72.5=4
add 72.5 to both sides
x=76.5
x-72.5=-4
add 72.5 to both sides
x=68.6
the minimum it can be set to is 68.5 and the max is 76.5
