Answer:multiply both numbers in the parenthesis by the number outside:

2n+4 +10=4n+20

add all like terms

2n+14=4n+20

subtract both sides by 14 and 4

2n-4n = 20 - 14

add or subtract like terms

-2n = 6

divide both sides by -2

n = -3

Can you please give me the cords of the points when the figure is rotated 90 degrees clockwise.
crimeas [40]
Don't you mean "coords," or (better yet) "coordinates?"

Look at line DG as an example.  It's vertical.  If you rotate the whole figure clockwise, then line DG becomes the horiz. line D'G.'  G' would have the coordinates (-1,-1), and D' (5,-1).  Plot these points G' and D' and see whether or not you agree.

Of the cartons produced by a company, 8% have a puncture, 7% have a smashed corner, and 0.7% have both a puncture and a smashed
Viktor [21]

Answer:

The probability that a randomly selected carton has a puncture or a smashed corner is 0.143

Step-by-step explanation:

we know that P(A∪B) = P(A) + P(B) - P(A∩B).

    since given that P(A) = Probability of getting puncture = 0.08

                                P(B) = probability of getting smashed corner = 0.07

                       P(A∩B) = probability of getting both puncture and smashed corner = 0.007

                    P(A∪B) = probability of getting any of them

   so P(A∪B) = 0.08 + 0.07 -0.007 = O.143
