<h3>
Answer: Choice C</h3>
The largest exponent here is 4, so that makes it a quartic.
There are 3 terms, so we have a trinomial. Each term is separated by either a plus or a minus.
Choice A shows a quartic polynomial. Choice B is a cubic polynomial. Choice d is a quadratic trinomial.
Answer:
- 3 ( 2x+1 ) 20
8x+5
_____________
8x+5×20 -3 ( 2×12.5+1 )
8×=100 -3 ( 25+1 )
100÷8= 12.5 -3 ( 26 )
×= 12.5
-3 ( 26 )
-3×2 + -3×6 = -6+ -18 = -24
-24

A slope of zero indicates that the line is horizontal, parallel to the x-axis and passes through all points in the plane with the same y-coordinate.
For the 2 given points both y-coordinates are - 8 and so the equation of the line is
y=-8
.
If you note this fact then it can be stated that the slope is zero without using the gradient formula.

Answer:
There are 70 sheep in the farm.
Step-by-step explanation:
Consider the provided information.
Let c represents the cows, s represents the sheep and p represents the pigs.
The number of cows and the number of sheep are in the ratio 6:5.
The number of sheep and the number of pigs are in the ratio 2:1.
The total number is 189.
Substitute the value of c and p in above.
Hence, there are 70 sheep in the farm.
