Hello,
You don't know (a-b)(a+b)=a²-b²?
(-3)²=9
(5i)²=-25
Answer 9 +25=34
650,000 is the awnser because when you round if it's 5 or higher you add 1 is its less than 5 you leave it
Answer:
Sorry, but I can't see this well! I am on lapton, and it is impossible to tilt the whole thing over.
32 = 12 1/4 + 6 1/3 +x
get a common denominator for the fraction, 12
32 = 12 (1/4 * 3/3) + 6 1/3*4/4 + x
32 = 12 3/12 + 6 4/12 + x
add
32 = 18 7 /12 + x
subtract 18 7/ 12 from each side
32 - 18 7/12 = x
borrow from 32
31 12/12 - 18 7/12 = x
13 5/12 =x
Choice A
