Hi Marisa255,
Solution:
First lets solve the given equation:
= 24 / 6 + 20
= 4 + 20
= 24
Now Lets solve A:
= 3(7 + 1)
= (3 x 7) + (3 x 1)
= 21 + 3
= 24
So we see that A and the equation given have the same answers.
Final Answer:
A. 3(7 + 1)
Answer:
x=9
Step-by-step explanation:
The goal is to combine our knowledge of geometry area and algebra skills to solve this problems.
We know area of rectangle is

where l is the length and w is the width. We know that one side is 3 less than the other side. We can use L or W but let use L. Let x replace L
One side is x, while the other side is

Both multiply to 54.





or

Distance. is positive so x=9
(x-5)(x+8) is your answer!
Answer:
Can we get more information?
Step-by-step explanation:
Answer:
By the 3rd hour,jenny must have covered 90kms
Paul covered 30kms after Jenny's 3rd hour and jenny still covered 30kms making a total of 150kms in the opposite direction. Therefore Paul needs not to cover additional hour so the answer =0hour
