The answer is A. 1,032 miles. 
You divide 42 gallons by 7. This is because you know how many miles can be reached per 7 gallons. 
41
172
x  6
------
1032

When you divide 42/7 you get 6. You then take 6 and multiply it by 172. 6x2 is 12, you carry the one, 6x7 is 42, plus the 1 that you carried, so you get 43, you carry the 4, 6x1 is 6, and you add the 4 to get 10. This brings your answer to 1, 032.

What is the radius of a circle whose equation is x2 y2 8x – 6y 21 = 0?
andrew11 [14]

we know that

the standard form of the equation of the circle is

(x-h)^{2} +(y-k)^{2}=r^{2}

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

x^{2} +y^{2} +8x-6y+21=0

<u>Convert to standard form</u>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^{2}+8x) +(y^{2}-6y)=-21

Complete the square twice. Remember to balance the equation by adding the same constants to each side.

(x^{2}+8x+16) +(y^{2}-6y+9)=-21+16+9

(x^{2}+8x+16) +(y^{2}-6y+9)=4

Rewrite as perfect squares

(x+4)^{2} +(y-3)^{2}=4

(x+4)^{2} +(y-3)^{2}=2^{2}

the center of the circle is (-4,3)

the radius of the circle is 2\ units

therefore

<u>the answer is</u>

the radius of the circle is 2\ units
