Answer:
(13c-5b)(a+4)
Step-by-step explanation:
Since both (13c) and (-5b) are being multiplied by (a+4), we can factor both of them out and put them in a bracket.
13c(a+4)−5b(a+4) = (13c-5b)(a+4)
Answer:
21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41

P( not study chemistry) = do not study chem)/total
=21/41

For math equations like this i use MathPaPa online and they give answers right away!! or you can you math away.
Your going to have to use the distance formula for these questions which is the square root of (x sub 2 - x sub 1) + (y sub 2 - y sub 1). For number 1 your coordinates are (-5,5) and (1,-2). Substituting these values into the formula your answer for number 1 is 9.2.
