Answer:
=x(x-1) +3x
= x^2-x+3x
=x^2 +2x
=x(x+2)
Step-by-step explanation:
the answer would be 41/5 or 8 1/5
10 to the power of 3 is 1000, and 400 divided by 1000 is 0.4 because you move the decimal place over 3 in the number 400 to get 0.4.
7(x - 3) + 3(4 - x) = -8
7x - 21 + 12 - 3x = -8
7x - 3x = -8 + 21 - 12
4x = 1
x = 1/4
Answer:
28/55
Step-by-step explanation:
total no of beads are 11
red beads are 7
and white beads are 4
no of ways to take 2 beads from 11 beads are 11c2
that is( 11*10)/2=55
no of ways to take 1 red bead from 7 is 7c1 that is 7
no of ways to take 1 white bead from 4 is 4c1 is that is 4
required probability is( 7*4)/55=28/55
