A + B + C = 518 ft^3
A = 1/3B, or 3A = B
B = C
A + B + C = 518 ft^3
1/3B + B + B = 518
7/3B = 518
B = 518×3/7 = 222 ft^3
A = 1/3B = 1/3×222 = 74 ft^3
C = B = 222 ft^3

Answer:

A + B + C = 518 ft^3

A = 1/3B, or 3A = B

B = C

A + B + C = 518 ft^3

1/3B + B + B = 518

7/3B = 518

B = 518×3/7 = 222 ft^3

A = 1/3B = 1/3×222 = 74 ft^3

C = B = 222 ft^3Step-by-step explanation:

Hi there!

Here are all the steps into simplifying this expression :

(4 × 2) + 15x + 49

Do the multiplication first → 4 × 2 = 8

8 + 15x + 49

Add the similar terms together → 8 + 49 = 57

15x + 57

Since there are no longer similar terms, the expression can not be simplified anymore and you are left with this expression as an answer :
