Answer:

Step-by-step explanation:

A^2 + B^2 = C^2 - Right Triangle Formula

8^2 + 7^2 = 6^2 - Plug it into the formula

64 + 49 = 36 - Solve

64 = 85 - Add B and C

21 - your answer

Hopefully this helps.

write the standard form of the equation of the circle with the given center and radius (6,4), r= square root of 7

REY [17]

The standard form of the equation of a circle is $(x-6)^{2}+(y-4)^{2}=7$ .

Solution:

Center of the circle = (6, 4)

Radius of the circle = $\sqrt{7}$

To find the equation of the circle:

General formula for the equation of a circle

$(x-h)^{2}+(y-k)^{2}=r^{2}$

where (h, k) is the center of the circle and r is the radius of the circle.

Here, h = 6, k = 4 and r = $\sqrt{7}$

$(x-6)^{2}+(y-4)^{2}=(\sqrt{7}) ^{2}$

$(x-6)^{2}+(y-4)^{2}=7$

Hence the standard form of the equation of a circle is $(x-6)^{2}+(y-4)^{2}=7$ .

Answer:

Yes, they have the same solution.

Step-by-step explanation:

Both of these equations have the same solution, just different steps.

To solve Ravi's equation, first we use the distributive property.

2(x+14) = 40

Multiply 2 by x and 14

2x + 28 = 40

Subtract 28 from both sides.

2x + 28 - 28 = 40 - 28

2x = 12

Divide by 2 on both sides.

2x/2 = x

12/2 = 6

so x = 6.

Fran's equation is the same equation as Ravi's second step.

Her equation of 2x + 28 = 40 is Ravi's after distributing 2.
