R + 9
Expression would be r+9=j
J represents the miles that Jessica rode. Since Jessica rode 9 miles farther, you must add 9 to the amount that roger rode.
Answer:
see explanation
Step-by-step explanation:
Given the polynomial
The rational zeros are all the possible factors of 
dived by all the possible factors of 
. Therefore we use the rational rots theorem to find all possible rational zeros.
To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.
Answer :2(4x)=(2×4)x (b)
Step-by-step explanation:
Answer:
7.4 · 10^4
Step-by-step explanation:
For scientific notation, multiplication is pretty simple.
In this case, you would only multiply the "regular" number by 2.
(3.7 · 2) · 10^4
= 7.4 · 10^4
However, if it were asking about multiplying the number with something else in scientific notation, in addition to what we did above, you'd add together the exponents.
I hope this helped!
