Answer:
The sum of three times a number and 4
-8
2(4) is 8, and because you are multiplying a negative by a positive, the result is negative.
Answer:
P(at least one wrong) = 1- P(all correct) =1-.25^6=1-1/4096=4095/4096. This assumes that the answers are picked at random. This kind of question is always the complement of an extreme binomial outcome.
The other number is 36 but if you are not counting 36, then it would be 18 but usually you would choose 36.
12*3=36
18*2
36*1=36
There are no other numbers above 12 other than 18 and 36 that has a multiple of 36
area=(b1+b2)*h all divided by 2
a=(12+12+8.7)*4.9 all divided by 2
a=32.7*4.9/2
a=160.23/2
a=80.12 sq. ft.
