Answer:
4x^2+4x-4
Step-by-step explanation:
8x^2 + 3x - 4x^2 + x - 4
= 8x^2 - 4x^2 + 3x + x - 4
= 4x^2 + 4x - 4
Oi :)
1) There are 3 significant digits

2)
15 Mi/h = 22 ft/s
3)

4)
There are 4 significant digitis. Leter C
2(x^2+6x+9) = 2(x+3)^2
So after divided by (x+3), answer will be:
2(x+3)
First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi
Next, we are going to use the Pythagorean theorem to find the distance from

to

:


d^2=1665


mi
Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi
We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved
16.2 miles.</span>
