Answer:
Step-by-step explanation:
To find the average of 4 things, we add those four things together and divide by 4. So, here we need to do the opposite. Since the last thing we would do to find the average is divide by four, we are going to start there and do the opposite. The average is 166. So...
166X4=664
Now instead of adding, we will subtract the three that we know, leaving the fourth. 664-200=464 464-150=314 314-180=134
So the weight of the fourth person is 134 pounds.
Answer: I’ll give you an example of how to do it by solving number 9 - h^2 + 8h + 16
Step-by-step explanation:
Step 1: Find two numbers that when you multiply them it gives you the first term’s coefficient multiplied by the last term’s coefficient (1x16 = 16) and when you add them it gives you the second term’s coefficient (8). The numbers in this case are positive 4 and positive 4.
Step 2: Create two parenthesis with the letter accompanied by the numbers. (h + 4)•(h+4). And that’s how you factor.
In case the first term is elevated to the third you will have to take out GCF (greatest common factor) first. If the numbers are too high like in the exercise number 15 you can also take out GCF and it will make it a lot easier to solve. Sometimes what you write on the parenthesis in the step 2 can be simplified, if that’s so then you would have to do it in order to get the correct answer.
Hope this helps you.
Factor dem groups
find greatest common factor
24=2*2*2*3
40=2*2*2*5
common is 2*2*2=8
answer is 8 groups
