ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
Answer: There are 50 students in the drama club and 34 students in the yearbook club
Step-by-step explanation:
34 + 16 = 50 There are 16 more drama club students than yearbook club students. 50 + 34 =84
you add up 138+225 and you get 363 then you subtract 482-363 this is how you set it up:
4 8 2
- 3 6 3
------------
you have to borrow because 3 does not go into 2 so you change the 8 into a 7 then you 10 to 2 and you get 12 so this is what it looks like:
4 7 12
- 3 6 3
-------------------
so you then subtract 12-3=9 then 7-6=1 then 4-3=1
so this is what it looks like
4 7 12
--- 3 6 3
--------------------
1 1 9
so on Sunday they rode 119 miles
