7 0

Answer:

x^2-1 has two terms without any negative exponent. so it is a polynomial.

Step-by-step explanation:

A polynomial is a expression with more than one terms.

The expression with negative exponent is not a polynomial.

Expression in the denominator is also not a polynomial

x^2-1 has two terms without any negative exponent. so it is a polynomial.

option B,C and D has negative exponents, so it is not a polynomial.

makkiz [27]

Answer:

5 Bags

Step-by-step explanation:

There are 75 carrots and 40 celery sticks.

If we want each bag to have the same combination, the greatest number of bags we can make is determined by the Greatest common divisor of the two numbers.

To find the Greatest common divisor of 70 and 40

<u>Step 1:</u> Express each number as a product of its prime factors

  • 40=2 X 2 X 2 X 5
  • 75=3 X 5 X 5

<u>Step 2:</u> Pick each pair of common factors.

  • 40=2 X 2 X 2 X 5
  • 75=3 X 5 X 5

The only factor common to both pairs is 5.

Therefore, the Greatest common divisor of 70 and 40 is 5.

The greatest number of bags that can be made is 5.

At the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner diameter is 22yd and its ou
jeka94
First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.

The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:

22/2 = 11 yards
32/2 = 16 yards

Then solve for the area of both circles.
π11^{2}= 121π ≈ <span>380.13 (area of the pool)</span>
π16^{2}= 256π ≈ <span>804.25 (area of the whole thing)
</span>
Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
804.25 - 380.13 = 424.12 (area of the walkway)

Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:

424.12 ÷ 6 ≈ 70.69

So you'll need 71 gallons of paint!

Hope I helped and let me know if you have any questions :)
