Step-by-step explanation:
Given that,
Sides of a triangle is 4 units, 6 units, and 7.21 units.
We need to find the area of a circle with a circumference that equals the perimeter of the triangle.
Perimeter of triangle = circumference of circle
4+6+7.21=2πr, r is the radius of circle
r = 2.73 units
Area of circle,
or
A = 24 sq units
So, the area of the circle is 24 square units.
X^2 + 4x -12 = (x+6)(x-2)
so
(x+6)(x-2)
---------------- = x - 2
x + 6
f(x) = x -2
because
if x = -6
then y = -6 - 2 = -8
(-6,-8) is the order pair
Answer:
5√3
Step-by-step explanation:
The <em>geometric mean</em> (GM) of two numbers x and y is the square root of their product.
Thus, the GM of x and y is √(xy).
The GM of 3√5 and 5√5
= √(3√5 × 5√5)
= √[3 × 5 × (√5)²]
= √(3 × 5 × 5)
= √(3 × 5²)
= 5√3
Hey!
The first step to solving this equation would be to rearrange it. It's better to rearrange it so that it is easier to solve.
<em>Original Equation :</em>
<span> −x = 4 − 3x + 6
<em>New Equation {Changed by Rearranging} :</em>
</span>-x = -3x + 4 + 6
Next we would group our like terms.
We can see that both 4 and 6 are whole numbers and can be added easily, so we'll start by grouping those like terms first.
<em>Old Equation :</em>
-x = -3x + 4 + 6
<span><em>New Equation {Created by Grouping Like Terms} :</em>
-x = </span><span>-3x + 10
Now we add 3x to both sides to get rid of the -3x on the left side of the equation.
<em>Old Equation :</em>
</span>-x = -3x + 10
<em>New Equation {Changed by adding 3x to Both Sides} :</em>
-2x = 10
Almost done! Our equation is one step closer to being solved.
Next, we will divide both sides by 10 to get x on its own.
<em>Old Equation :</em>
-2x = 10
<em>New Equation :</em>
x = 5
Our equation can now no longer be simplified any farther. Therefore, it is officially solved!
<span><em>The value of x in the equation −x = 4 − 3x + 6 is </em> x = 5.
Hope I helped!
