Answer:
is not a polynomial.
Step-by-step explanation:
Given : an expression
We have to check whether given expression is a polynomial or not.
An expression is said to be polynomial if it is the collection of constant and one or several variables having non negative integer power or degree.
Example :
For the given expression the variable term is X is having power of -6 which is negative.
Hence, is not a polynomial.
It is A it is being multiplied by -3
Answer:
strange phrasing of a question
If one assumes that the "observation" was from 3:00 pm - 5:00 pm (2 hours)
and the ball was ONLY "bounced" 10 times (3+7)
we can can say that the rate was 10 bounces/2 hours or 5 b.p.h. (bounces per hour)
Step-by-step explanation:
Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
Step-by-step explanation
Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.
<span>We will call A to the number of hours traveled by Annie and B the number of hours travelled by Brian. Then Annie traveled 5 times plus 2 hours than Brian, that is
A = 5 * B + 2. And the total number traveled by both of them was 20, so: A + B = 20
Next step is solve both equations putting value of A in the second equation:
5 * B + 2 + B = 20 that is the same than:
6 * B = 18 and:
B = 3 then:
A = 5 * 3 +2
A = 17
The solution is Annie traveled 17 hours and Brian only traveled 3 hours.</span>
