Answer:
Step-by-step explanation:
32a²b² = 2 * 2*2*2*2 * a² * b²
36a²c² = 2 * 2 * 3 * 3 * a² * c²
16ab³ = 2 * 2 * 2* 2 * a * b³
Greatest common factor = 2*2*a = 4a
32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
It C I think
Sorry if wrong
Answer:
let me make it its equation I have done this but if this will work have a good day
Answer:
40 and 35
Step-by-step explanation:
If we say the first car uses x gallons then the second car must use 75 - x gallons.
The distance travelled is the number of gallons used * the efficiency of the car.
20x + 15(75-x)=1325
20x + 1125 - 15x = 1325
5x = 200
x = 40
This means that the first car uses 40 gallons and the second car uses 75-40= 35 gallons
Answer:
Step-by-step explanation:
Hello
Simplify :
9 (1 - r) + 3r
= 9 - 9r + 3r
= 9 - 6r
= 3(3 - 2r)
