Write down the value of 2jk - 10j when j = 9 and k = 2 Write down only the number, nothing else

-54

Step-by-step explanation:

2jk - 10j

Let j = 9 and k=2

2*9*2 - 10 *9

36 - 90

-54

78.59 is the mean

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
