Add the 5 amounts:
-10 + -23 = -33
-33 + 8 + 7 + 3 = -15 cents
now divide by the number of changes (5)
-15 / 5 = -3 cents
the mean change is -3 cents

(5t - 3) · (3t + 7)
t = 6
<u>Step 2: Evaluate</u>
- Substitute in <em>t</em>: (5(6) - 3) · (3(6) + 7)
- (Parenthesis) Multiply: (30 - 3) · (18 + 7)
- (Parenthesis) Subtract: 27 · (18 + 7)
- (Parenthesis) Add: 27 · 25

Answer:
D is the one
Step-by-step explanation:
Answer: 348in^2
Step-by-step explanation:
8 x 9 = 72
72 x 2 = 144in^2 (front and back)
8 x 6 = 48
48 x 2 = 96in^2 (sides)
9 x 6 = 54
54 x 2 = 108in^2 (top and bottom)
Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)
