Answer:
3x²+(-27x) +0
Step-by-step explanation:
The given expression is :
x + 3x² – 28x
We need to solve this in the form of ax²+bx+c.
we can write the given expression as :
3x²-28x+x = 3x²-27x
= 3x²+(-27x) +0
If we compare the given expression with the general expression, we find that,
a = 3, b = -27 and c = 0
Hence, the required equation is 3x²+(-27x) +0.
Answer:3/4
Step-by-step explanation:60 minutes divided by 4 is 15. 3 15 minute increments is 45. 45 minutes is 3 /4 of an hour.

<u>Our problem:</u>
![\frac{2}{3} \div \frac{4}{5} = unknown](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%20%5Cdiv%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%3D%20unknown)
How to solve?
Find the reciprocal (opposite) of 4/5, then multiply. Simplify if necessary.
<u>Find the reciprocal:</u>
![\frac{2}{3} \times \frac{5}{4} = unknown](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Ctimes%20%20%5Cfrac%7B5%7D%7B4%7D%20%20%3D%20unknown)
<u>Multiply:</u>
![\frac{2}{3} \times \frac{5}{4} = \frac{10}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Ctimes%20%20%5Cfrac%7B5%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B10%7D%7B12%7D%20)
<u>Simplify:</u>
![\frac{10 \div 2}{12 \div 2} = \frac{5}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%20%5Cdiv%202%7D%7B12%20%5Cdiv%202%7D%20%20%3D%20%20%5Cfrac%7B5%7D%7B6%7D%20)
5/6 is your answer.
Yeah I’m pretty sure it is a rational number
