I need help with the equation.
natulia [17]

Answer:

(x - 3)² + (y + 9)² = 25

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

Given area = 25π , that is

πr² = 25π ( divide both sides by π )

r² = 25 ( take the square root of both sides )

r = \sqrt{25} = 5

With centre (h, k) = (3, - 9 ) and r = 5 , then

(x - 3)² + (y - (- 9) )² = 5² , that is

(x - 3)² + (y + 9)² = 25

What is the width of a rectangle with length 14cm and area 161 cm^2
Inessa05 [86]

Answer:

Step-by-step explanation:

The area of a rectangle can be found with the formula A = l*w, where l is the length of the rectangle and w is the width.

From the given problem statement, we know that l = 14 and A = 161, so we can fill in those values in the formula anbd solve for w to get the width:

A = l*w

161 = 14w

Divide both sides by 14 to isolate w by itself:

\frac{161}{14} = \frac{14w}{14}

w = 11.5

Find
shepuryov [24]

Answer:

The two odd numbers are 15 and 17

Step-by-step explanation:

Given

<em>Let the odd numbers be represented with x and y</em>

<em>Let x be the greater number</em>

<em></em>x + 5y = 92<em></em>

<em></em>

<em>Required</em>

Find x and y

Since x and y are consecutive odd numbers and x is greater, then

x = y + 2

Substitute y + 2 for x in x + 5y = 92<em></em>

<em></em>y + 2 + 5y = 92<em></em>

<em></em>

Collect Like Terms

<em></em>y + 5y = 92 - 2<em></em>

<em></em>6y = 90<em></em>

Divide both sides by 6

\frac{6y}{6} = \frac{90}{6}

y = \frac{90}{6}

y = 15

Substitute 15 for y in x = y + 2

x = 15 + 2

x = 17

<em>Hence; the two odd numbers are 15 and 17</em>

Juliette [100K]

Answer:

12x^2+9x

Step-by-step explanation:

The formula of the area of a triangle is \frac{bh}{2}. Plugging in the given base and height values, you get \frac{(4x+3)(6x)}{2}=\frac{24x^2+18x}{2}=12x^2+9x. Hope this helps!
