Answer:
The answer is c
Step-by-step explanation:
Answer:
Area of room = 21 * 16
= 336 m²
Area of Carpet = (21 - 1)* (16-1)
= 20*15
= 300
Area of border = Area of room - Area of carpet
= 336 - 300
<h3>= 36 m².</h3>
Answer:
20%decrease
Step-by-step explanation:
sorry I'm bad at explaining things
38%
What I did:
14+5=19
19/50
19 ÷ 50 = 0.38
0.38 x 100 = 39%
Using the definition of polynomial, it is found that options D and E are polynomials.
D. ![4x^4 - 10](https://tex.z-dn.net/?f=4x%5E4%20-%2010)
E. ![15x^2 + 3x - 2](https://tex.z-dn.net/?f=15x%5E2%20%2B%203x%20-%202)
-----------------------
A polynomial of the nth degree is defined by the following equation:
![p(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_2x^2 + a_1x^1 + a_0](https://tex.z-dn.net/?f=p%28x%29%20%3D%20a_nx%5En%20%2B%20a_%7Bn-1%7Dx%5E%7Bn-1%7D%20%2B%20...%20%2B%20a_2x%5E2%20%2B%20a_1x%5E1%20%2B%20a_0)
The exponents n are integers, and have to be non-negative.
- In options A and C, there are negative exponents(
, and thus, they are not polynomials. - In option B,
, that is, a fractional exponent, thus also not a polynomial. - In options D and E, the exponents are integers and non-negative, thus they are polynomials.
