Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
Answer:
Simplify them to the lowest.
What's the GCF( Greatest Common Factor). It's 8. So divide both sides by 8.
24/8 = 3
56/8 = 7
so it's
3 dogs to 7 cats

Step-by-step explanation:
<u>Step 1: Determine the area of the left rectangle</u>
We can tell that the total shape seems like two rectangles glued together. We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them. Lets first solve the left rectangle.
<u>Step 2: Determine the area of the right rectangle</u>
<u>Step 3: Determine the total area</u>
Answer:
Answer:
The answer is "Yes, 6 = 6"
Step-by-step explanation:
If you substitute 2 for A, you would get 4 + 2 is less than or equal to 6, which is true because 6 = 6.
Since the sphere is located at the center and has radius 5.
Out of the following given points,
(5,5,-5) will lie on the sphere, where x and y coordinates will be positive and z coordinate will be negative.
This is because the radius of the circle is 5 units.
