Anna opens a new savings account with a $500 deposit. She makes regular deposits of $50 each week. Suppose she makes a one-time withdrawal of $75. Which TWO expressions represent the balance of the savings account after x weeks? A.) x + 425
B.) 50x + 425
C.) 500x - 75
D.) 50(x - 75)
E.) (50x + 500) - 75

Step-by-step explanation:

Balance:

Correct choice B and E

B

Step-by-step explanation:

50x represents her weekly deposit, and the 425 represents her original %500 with her $75 withdraw.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
