I think its C (4-4) / mark brainlyest
2(3u-8)= 38
6u-16=38
take 16 on the other side..
6u = 38 +16
6u = 54
u = 9
Answer:
iii. (l + m - n)(l - m + n)
vi. (5a -b) ( 5b - a)
Step-by-step explanation:
iii. l² - (m - n)²
= (l + m - n)(l - m + n)
vi. 4(a+b)² - 9(a-b)²
= (2(a+b))² - (3(a-b))²
= (2(a+b) + 3(a-b)) (2(a+b) - 3(a-b))
= (2a+2b + 3a - 3b) (2a+2b - 3a + 3b)
= (5a -b) ( 5b - a)
Answer:
There are 40 students in the photography club.
Step-by-step explanation:
Given that:
Percent of people not going to art show = 15%
Number of people not going to art show = 6
Let,
x be the number of students in the photography club
15% of x = 6
0.15x = 6
Dividing both sides by 0.15
Hence,
There are 40 students in the photography club.
