Answer:
84. What you did is right.
Step-by-step explanation:
A parallellogram's area is b x h. So the equation is 7 x 12=84.
S=d/t so in this case it's 75/12 which is 6.25. Round it and you got 6 miles per hour.
Answer:
<em>( x + 13 )^2 + ( y + 6 )^2 = 1; Option A</em>
Step-by-step explanation:
<em>~ The question we have at hand is: x^2 + y^2 + 26x + 12y + 204 = 0 ~</em>
Let us apply the circle equation ( x - a )^2 + ( y - b )^2 = r^2 ⇒ provided r is the radius, centered at point ( a, b )
1. First rewrite x^2 + y^2 + 26x + 12y + 204 = 0 in the standard form of circle equation: x^2 + y^2 + 26x + 12y + 204 = 0
2. Now move the loose number to the right side: x^2 + 26x + y^2 + 12y = -204
3. Let us now group variables: ( x^2 + 26x ) + ( y^2 + 12y ) = -204
4. Convert x to square form: ( x^2 + 26x + 169 ) + ( y^2 + 12y ) = -204 + 169
5. Convert to square form: ( x + 13 )^2 + ( y^2 + 12y ) = -204 + 169
6. Convert y to square form: ( x + 13 )^2 + ( y^2 + 12y + 36 ) = -204 + 169 + 36
7. Convert to square form, and simplify: ( x + 13 )^2 + ( y + 6 )^2 = 1
<em>Answer: ( x + 13 )^2 + ( y + 6 )^2 = 1</em>
Answer:
25 + x = 44
Step-by-step explanation:
Substitute the words with the math symbols.
25 more than a number x is the same as 44
more than means to +
is the same as means =
25 more than a number x is the same as 44
25 + x = 44
25 + x = 44
