Answer:

(x + 7)² + (y - 8)² = 49

Step-by-step explanation:

Circle Equation: (x - h)² + (y - k)² = r²

(h, k) is center

<em>r</em> is radius

Step 1: Define

h = -7

k = 8

r = 7

Step 2: Substitute

(x - -7)² + (y - 8)² = 7²

(x + 7)² + (y - 8)² = 49

(x³ + ³) / (x - y)<br> Do not include parentheses in your answer.

Lubov Fominskaja [6]

The simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

<h3>Complete question</h3>

Simplify the expression: (x³ + (-y)³) / (x - y)

Do not include parentheses in your answer.

<h3>How to simplify the expression?</h3>

The expression is given as:

$\frac{x^3 + (-y)^3}{(x - y}$

Open the inner bracket

$\frac{x^3 -y^3}{(x - y}$

Apply the difference of two cubes to the numerator

$\frac{(x-y)(x^2+xy+y^2)}{(x - y}$

Cancel out the common factors

$x^2+xy+y^2$

Hence, the simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

You have to use a proportion.

3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
