Answer:

Step-by-step explanation:

equation of the circle (x - 4)² + (y - 1)² = 9

Length of the vertical leg comes from subtracting the y values of (4, 1) and (4, 3) 3 - 1 = 2

Horizontal leg = √(3² - 2²) = √5

Which of the following is NOT a solution to the linear equation y=3x+2?

Ipatiy [6.2K]

Answer:

(3,10)

Step-by-step explanation:

When x is 3

${ \bf{y = 3x + 2}} \\ { \bf{y = (3 \times 3) + 2}} \\ { \bf{y = 11}}$

y is 11, and this is invalid because it is not at accord.

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.

ANEK [815]

The area of a rectangle is the product of its dimensions

The dimensions of the rectangle are: $\mathbf{Length = a -5}$ and $\mathbf{Width = a^2 + 5a + 25}$

The area is given as:

$\mathbf{Area = a^3 - 125}$

Express 125 as 5^3

$\mathbf{Area = a^3 - 5^3}$

Apply difference of cubes

$\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}$

$\mathbf{Area = (a - 5)(a^2 + 5a + 25)}$

The area of a rectangle is:

$\mathbf{Area = Length \times Width}$

So, by comparison:

$\mathbf{Length = a -5}$

$\mathbf{Width = a^2 + 5a + 25}$
