Step-by-step explanation:
Well, if 1 gallon of gas = 1 hour then
2 hours would be 2 gallons so only 11 gallons of gas would be left in the tank and
13 hours would be 13 gallons, so 0 gallons of gas would be left in the tank
Answer:
1. 800 cm squared
2. 152 cm squared
Step-by-step explanation:
let break it down
1. 800 cm squared
20 * 7 = 140
20 * 6 = 120
38 - 20 = 18
30 * 18 = 540
now add all of them together
140 + 120 + 540
100 + 100 + 500 = 700
40 + 20 + 40 = 100
700 + 100 = 800 cm squared
2. 152 cm squared
16 * 10 = 160
2 * 2 + 2 * 2 = 4 + 4 = 8
160 - 8 = 152 cm squared

Answer:
-36x^3 - 69x^2 - 34x - 5
Step-by-step explanation:
(4x + 5) (3x + 1) -3 (x + 1)
(4x + 5) (3x + 1) ( -3x - 1)
12x^2 + 4x + 15x +5
Combine like terms
12x^2 + 19x + 5 (-3x - 1)
-36x^3 -57x^2 - 15x^2 -5
Combine like terms
-36x^3 - 69x^2 - 34x - 5
