Answer:
3b is the answer
3a+2b-3a+b
3a-3a+2b+b
2b+b
Step-by-step explanation:
The first step I did is switch up the equation so that the like terms are next to each other. So the a’s are next to each other and the b’s are next to each other. Then I subtracted 3a-3a and got 0 and in the last step I added the 2b + b and got 3b.
9a^2- 4b^2
First, Apply the distributive property 3a(3a)+3a(−2b)+2b(3a)+2b(−2b)
Second Simplify the term. 3a(3a)+2b(−2b)
Third, Simplify Each term.
3⋅3a2+2b(−2b)
9a2+2b(−2b)
9a2+2⋅−2b2
= 9a2−4b2

Sorry. :(((
Hope this helped, tho. :))
A.If you multiply two numbers greater than 5, then their product is greater than 25.
B.If the product of two numbers is even, then both numbers must be even.
C.If x ∙ y = 1, then x or y must equal 1.
D.If two times a number is greater than 16, then the number must be greater than 9.

B. At the rate given, how many kilometers can Mikaela bike in 1 hour?
____________________
c. If Mikaela runs for 1 hour and bikes for 1 hour at the rates given, how far will she travel?
____________________
Mikaela can run 10 kilometers in 1 hour.
Mikaela can bike 25 kilometers in 1 hour.
If Mikaela runs for 1 hour and bikes for 1 hour at the given rates, she will travel a totaldistance of 35 kilometers.
We have,
A.
To find the number of kilometers Mikaela can run in 1 hour, we can set up a proportion using the information given:
5 kilometers / 0.5 hour = x kilometers / 1 hour
Cross-multiplying, we get:
(5 kilometers) x (1 hour) = (0.5 hour) x (x kilometers)
Simplifying:
5 kilometers = 0.5x kilometers
To isolate x, we can divide both sides of the equation by 0.5:
5 kilometers / 0.5 = x kilometers
x = 10 kilometers
B.
Similarly, to find the number of kilometers Mikaela can bike in 1 hour, we can set up a proportion:
20 kilometers / 0.8 hour = x kilometers / 1 hour
Cross-multiplying:
(20 kilometers) x (1 hour) = (0.8 hour) x (x kilometers)
Simplifying:
20 kilometers = 0.8x kilometers
Dividing both sides by 0.8:
20 kilometers / 0.8 = x kilometers
x = 25 kilometers
C.
To find the totaldistance Mikaela will travel if she runs for 1 hour and bikes for 1 hour, we can simply add the distances:
Distance = distance run + distance biked
Distance = 10 kilometers + 25 kilometers
Distance = 35 kilometers
Therefore,
Mikaela can run 10 kilometers in 1 hour.
Mikaela can bike 25 kilometers in 1 hour.
If Mikaela runs for 1 hour and bikes for 1 hour at the given rates, she will travel a totaldistance of 35 kilometers.
