open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
Answer:
0.00397
Step-by-step explanation:
I am taking a guess. Like I saw this example (5/9)(4/8)(3/7)(2/6)=120/3024=0.0397
Or (5C4)/(9C4)=0.0397 - from chisnau
Follow those steps, but add your numbers . I added one zero bassed on the problem: There are 9 students in a class: 5 boys and 4 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?
Hope I helped in some way!
Is it on edmentum? Btw happy Friday hope you have a bless day
Answer:
25x² − 20x + 4
Explanation:
(5x − 2)²
= (5x + −2)(5x + −2)
= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)
= 25x² − 10x − 10x + 4
= 25x² − 20x + 4
