When factoring this expression 20b-16, find the GCF (greatest common factor) among both terms. For this case, it is 4 which is the GCF. Therefore,
20b - 15 is equal to 4(5b - 4)
The factors of the expression are 4 and 5b-4.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
A set of equation can be set up:
a=b+15
3(a+b)=345
where a is the faster and b is the slower bus.
substitute b+15 into the second equation, so 6b+45=345, and 6b=300, therefore b=50.
we can then figure out that a=65
Answer:
285, 629, 7392, 15708,43695
Step-by-step explanation:
If you add the digits of the number together, it should be divisible by 9. If it isn't, then it must be a multiple of only 3, not 9.
Answer:
113 (d)
Step-by-step explanation:
Since the room is square-shaped, you square root the area (12,769) to find the length of each wall. You will get the answer 113. To check this answer multiply 113 by 113 and make sure you get the correct area; it works, so you know the answer is D.
