Step-by-step explanation:
What do you mean by long division.....
1. Write the problem.
2. Write all numerators above the common denominator- x.
3. Reorder the terms and you get the answer.
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
1x is the same as x
The formula for the volume of a cube is V = a³ when a = the length of one side.
So, if we say a = 5xy, then...
V = (5xy)³
V = 125x³y³
The volume of the cube is 125x³y³ centimeters³
Answer:
(x + 12)² + (y + 32)² = 1031
Step-by-step explanation:
137 + 64y = -y² - x² - 24x
Arrange the terms in descending powers of x and y.
x² + 24x + y² + 64y = -137
Complete the squares for x and y
(x² + 24x + 144) + (y² + 64y + 1024) = -137 + 144 + 1024
Write the equation as the squares of binomials of x and y
(x + 12)² + (y + 32)² = 1031
This is the equation of a circle with centre at (-12, -32) and radius r = √1031.
