Answer: (x–2) and (10x+7)
Step-by-step explanation:
10x^2 – 13x – 14=
10x^2 – 20x + 7x – 14=
10x(x–2) + 7(x–2)=(x–2)(10x+7) ==> 3rd option
Answer:
Any values for n that are greater than 4 will satisfy the expression
Step-by-step explanation:
We have the expression
7n/4 > 7 solve for n...
7n > 28 multiply by 4 on both sides
n > 4 divide by 7 on both sides,
n is greater than 4, so any value for n greater than 4 will satisfy the inequality
You can use greatest common factor(gcf)
list the factors of 18 and 30.
18- 1, 2, 3, 6, 9, 18
30- 1, 2, 3, 5, 6, 10, 15, 30
now the factor that is greatest is 6.
this mean you can use the largest square tile of 6in by 6in without overlap or cutting.
Answer:
I think A or D but i'm stuck on D
Step-by-step explanation:
Answer:
The speed of plane against wind S 1 = 1020 kmph And
The speed of plane with wind S 2 = 1260 kmph
Step-by-step explanation:
Given as :
The distance of airplane against the wind = D 1 = 3060 km
The time taken in against the wind = T 1 = 3 hours
The distance of airplane with the wind = D 2 = 7560 km
The time taken in with the wind = T 2 = 6 hours
Now, Speed of plane against the wind = 
So, S 1 = 
Or, S 1 =
= 1020 kmph
Similarly
Speed of plane with the wind = 
Or, S 2 = 
Or, S 2 =
= 1260 kmph
Hence The speed of plane against wind S 1 = 1020 kmph And
The speed of plane with wind S 2 = 1260 kmph Answer
