Answer:

Center (6 , -5)   and radius = 3

Step-by-step explanation:

The Standard equation of circle can  be written as

(x - a)² + (y - b)² = r²

with center (a , b)   and radius  = r

Now from given circle equation

(x - 6)² + (y +5)² = 9

so, from here center of circle (6 , -5) and radius = 3

a trapezoid has base lengths of (6x-1) units and 3 units. Its midsegment has a length of (5x-3) units. What is the value of x?
vodka [1.7K]
1. You have that:

 - The<span> lengths of the bases are (6x-1) units and 3 units.
 - The midsegment has a length of (5x-3) units.

 2. To solve this exercise, you must apply the formula for calculate the length of the midsegment of a trapezoid, which is shown below:

 Midsegment=Base1+Base2/2

 As you can see, the midsegment is half the sum of the bases of the trapezoid.

 3. When you substitute the values, you obtain:

 (5x-3)=[(6x-1)+3]/2

 4. Now, you can solve the problem by clearing the "x":
</span>
 (5x-3)=[(6x-1)+3]/2
 2(5x-3)=6x-1+3
 10x-6=6x+2
 10x-6x=2+6
 4x=8
 x=8/4
 x=2

Let p = x2 + 6.<br> Which equation is equivalent to (22 + 6)2 – 21 = 4x2 + 24 in terms of p?
Alona [7]

Answer:

\frac{35}{4} =p

Step-by-step explanation:

p=x^{2} +6,

(22+6)2-21=4x^{2} +24

44+12-21=4x^{2} +24

35=4x^{2} +24,

If you factor out the equation, you get that 35=4p(if you factor it out)

Therefore,\frac{35}{4} =p
