Answer:
Step-by-step explanation:
2a^-a-13=2
Subtract 2 from both sides :
2a^2-a-13=2=2-2
2a^2-a-15=0
Factor left side of the equation :
(2a+5) (a-3)=0
Set factors equal to 0 :
2a+5=0 or a-3=0
a=-5/2 or a=3
So,
I'm assuming you are asking:
6 tons = x lbs.
The conversion from tons to pounds is:
1 ton = 2000 lbs.
So:
6 tons = 2000 * 6 = 12,000 lbs.
The simplified form is 20x^2. Because you 2x*2, you get 4x. You multiply that by 5x, and then you get your answer.
Answer:
The domain is t ≥ 0
The range is D ≥ 0
Step-by-step explanation:

D(t) = 100t + d₀
t is the time measured in hours.
d₀ is the initial position of the train.
We can assume the distance they go is not negative so...
The domain is t ≥ 0
The range is D ≥ 0
Answer:
Step-by-step explanation:
SAS = side- angle- side
It requires two sides and the included angle be congruent.
Given one congruent side and one congruent adjacent angle.
<u>In addition to what is given we need the other side be congruent too:</u>
