(2h3 + 6h) + (3h3 - 7h - 3) standard form sum or difference.​
worty [1.4K]

Answer:

5h^3- h - 3

Step-by-step explanation:

Given

(2h^3 + 6h) + (3h^3 - 7h - 3)

Required

Standard form

We have:

(2h^3 + 6h) + (3h^3 - 7h - 3)

Remove bracket

(2h^3 + 6h) + (3h^3 - 7h - 3) =2h^3 + 6h + 3h^3 - 7h - 3

Collect like terms

(2h^3 + 6h) + (3h^3 - 7h - 3) =2h^3 + 3h^3+ 6h  - 7h - 3

(2h^3 + 6h) + (3h^3 - 7h - 3) = 5h^3- h - 3

Hence, the standard form is:

5h^3- h - 3

Syracuse and New York City are 240 miles apart. One car left Syracuse heading for New York City at an average of 65 mph. A secon
bazaltina [42]
Let x be the distance from Syracuse where they pass. The first car travels a distance of x in time x/65 while the second car travels a distance 240-x in time (240-x)/55. They pass at the same time after leaving their starting points so x/65=(240-x)/55.
Cross-multiplying we get: 55x=65(240-x)=15600-65x, 120x=15600, x=15600/120=130 miles.
They pass 130 miles from Syracuse.

I only know (b) and 28 (c)
(b) Multiples of 120= 120,240,360,480,600
Multiples of 150= 150,300,450,600
Both numbers have 600 as their first common multiple so the ANSWER is 600
28. (a) Common factors of 24= 1,2,3,4,6,8,12,24
Common factors of 64= 1,2,4,8,16,32,64
8 is the only common factor for both 24 and 64 so 8 is the ANSWER

The total travel time for the ranger to get to the car is the sum of the travel time in the forest and the travel time on the ro
Yuki888 [10]

Answer:

[ext]T(x) = 2C / Speed[/ext]

Step-by-step explanation:

[ext]Time taken for the Ranger to get to the car = Sum total time taken to travel in the forest and on the road[/ext]

Since [ext]distance of the Ranger to the car = C[/ext]

[ext]Time taken = distance/speed[/ext]

[ext]Total Time taken T(x) = 2 * C / speed[/ext]

T(x) = 2C / speed
