The equation of a circle in general form is x2+y2+22x+14y−55=0 . What is the equation of the circle in standard form?

ra1l [238]

$x^2+y^2+22x+14y-55=0 \\\\x^2+22x+y^2+14y=55\\\\(x^2+22x+121)-121+(y^2+14y+49)-49=55\\\\(x+11)^2+(y+7)^2-121-49=55\\\\
(x+11)^2+(y+7)^2-170=55\\\\(x+11)^2+(y+7)^2=55+170\\\\\boxed{(x+11)^2+(y+7)^2=225}$

Kori bought 56 boxes of tiles from the home improvement store, which was es 4/7 of the total number of boxes that they had. How

dimaraw [331]

Answer:

98 boxes

Step-by-step explanation:

If 56 is $\frac{4}{7}$ of the total, we can set up an equation like this:

$56=\frac{4}{7}*T$

Where T is the total number of boxes.

Solving for T gives us the answer:

$56=\frac{4}{7}T\\T=\frac{56}{\frac{4}{7}}\\T=56*\frac{7}{4}\\T=98$

There were 98 boxes in total.
