Mathematics
1 answer:
dybincka [34]3 years ago
5 0

Step-by-step explanation:

Use the quadratic formula to find the solutions.

−b±√b2−4(ac)2a-b±b2-4(ac)2a

Substitute the values a=9a=9, b=0b=0, and c=−81c=-81 into the quadratic formula and solve for xx.

x=±3x=±3

The final answer is the combination of both solutions.

x=3,−3x=3,-3

What is the difference and what is their value?
anastassius [24]

Answer:

Look below.

Step-by-step explanation:

For one, g+g+g+g does not equal g^4. That equals g·g·g·g.

But like you said, 4g = g·g·g·g as well, so shouldn't they be equal?

The answer is more simple than you might expect:

We'll do the second one first. I don't know why, that is just how it is going to be done.

Let's assign a value to 'g'. We'll call it g = 3.

3 to the 4th power is

1) 3·3 = 9

2) 9·3 = 27

3) 27·3 = 81.

So g^{4} = 81.

But, you probably figured out, with g = 3, that 4g = 12, since 3·4 = 12.

Obviously, 81 ≠ 27, meaning these are not the same, and that is the main difference.

A rectangular wall is 16 feet wide by 24 feet long. A contractor is looking to tile the wall with square tiles with a side lengt
tamaranim1 [39]

Answer:

96 square tiles are needed

Step-by-step explanation:

To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.

Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2

The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2

the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96
