Answer:
B.
Step-by-step explanation:
f(x) has two complex roots and one real root.
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
Answer:
Khalid = 140 mph
Jesse = 150 mph
Jesse has the faster train
Step-by-step explanation:
Khalid is travelling 140 mph because 280/2 is 140
Jesse is travelling at 150 mph because just like the question stated, y=150x where "x" is the total hours they traveled and 150 is the distance she traveled.
Jesse is faster because 150>140
The difference between the areas of Alaska and Rhode Island in square miles is 481.
What is "difference" in mathematics?
One of the most crucial mathematical operations, which is obtained by removing two integers, produces difference in mathematics. It reveals how much one number deviates from another. To determine how many numbers are between the two supplied numbers is the goal of finding the difference in math. The difference in mathematical notation is minus (-).
Given that Rhode Island is 392 square miles in size overall and Alaska is 873 square miles, the following calculation must be done to discover the difference between them:
873 - 392 = X
481 = X
Therefore, the difference in square miles is 481.
