(1/3)*h-(4*((2/3)*h-3)) = (2/3)*h-6 // - (2/3)*h-6

(1/3)*h-(4*((2/3)*h-3))-((2/3)*h)+6 = 0

(1/3)*h-4*((2/3)*h-3)+(-2/3)*h+6 = 0

h/3-4*(2/3*h-3)+(-2*h)/3+6 = 0

(-4*3*(2/3*h-3))/3+h/3+(-2*h)/3+(3*6)/3 = 0

h-4*3*(2/3*h-3)-2*h+3*6 = 0

18-7*h-2*h+36 = 0

18-9*h+36 = 0

54-9*h = 0

(54-9*h)/3 = 0

(54-9*h)/3 = 0 // * 3

54-9*h = 0

54-9*h = 0 // - 54

-9*h = -54 // : -9

h = -54/(-9)

h = 6

h = 6

ANSWER ASAP!! Find the area of a triangle with legs that are: 12 m, 15 m, and 9 m.
Setler79 [48]

Answer:

<h2>54m²</h2>

Step-by-step explanation:

<h3>METHOD 1:</h3>

You can use the Heron's formula:

A=\sqrt{p(p-a)(p-b)(p-c)}

where

<em>p</em><em> - half of perimeter</em>

<em>a, b, c</em><em> - lengths of sides</em>

We have

a=12m;\ b=15m;\ c=9m

Calculate:

p=\dfrac{12+15+9}{2}=\dfrac{36}{2}=18\ (m)\\\\A=\sqrt{18(18-12)+(18-15)(18-9)}\\\\A=\sqrt{(18)(6)(3)(9)}\\\\A=\sqrt{2916}\\\\A=54\ (m^2)

<h3>METHOD 2:</h3>

Let's check that it is not a right triangle.

If the sum of the squares of the two shorter sides is equal to the square of the longest side, then this triangle is rectangular.

We have

9m < 12m

Check:

9^2+12^2=81+144=225\\15^2=225

This is a right trianglr wherew 9m and 12m are legs and 15m is a hypotenuse.

The formula of an area of a right triangle is:

A=\dfrac{ab}{2}

<em>a, b</em><em> - legs</em>

Substitute:

A=\dfrac{(9)(12)}{2}=\dfrac{108}{2}=54\ (m^2)

Which graph shows the correct solution to the inequality below?
Assoli18 [71]

Answer:

Third Option

Step-by-step explanation:

3x + 18 > 6x - 9

We have to find the value of x for this

Subtract 18 from both sides to leave 3x alone

3x > 6x - 27

Subtract 6x from both sides to be able to find the value of x

-3x > -27

Divide by -3 on both sides

x > 9

The answer would be the third option, since X is anything greater than 9
