For this case we must find the product of the following expression:

We apply distributive property, which states that:

So:
We add similar terms:

Answer:
Option D
To answer this question you basically have to add up day 1, day 2 and day three then take it away from 30 so.....
7.7+6.4+8.0=22.1
30-22.1=7.9 so they have 7.9 miles left to walk
Answer:

Step-by-step explanation:
Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r

49+576=

525=c^2

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals

cos=

then we find secant which is the reciprocal of cos so we flip the numbers and that equals

1 gallon=8 pints
so, 5 pints + 3 pints = 8 pints= 1 gallon
and, 6 gallons + 3 gallons= 9 gallons
Finally, 1 gal+9 gal= 10 gallons
Answer: 10 GALLONS
Answer:
A
Step-by-step explanation:
Given
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ±
= ± 5
Solutions are x = 5 and x = - 5
