Step-by-step explanation:
Let the painting's width be w inches and length be l inches.
w + 6 = 2l
w = 2l - 6 --(1)
2w + 2l = 84 --(2)
sub (1) into (2):
2(2l - 6) + 2l = 84
2l - 6 + l = 42
3l = 48
l = 16
when l = 16, w = 2(16) - 6 = 26
area of painting = lw = 16 x 26 = 416square inches
Therefore, only statements 1, 3 and 5 are true

The plane's airspeed is 140:)
Answer:
a. <u><em>14:45pm</em></u> (It's really easy to convert to a 24-hour clock time, all you need to do is add 12 hours onto the hour. Eg. 2 + 12 = 14 so it will be 14:45.pm
b. The length of time between 11:45am and 2:45pm is <em><u>3 hours.</u></em>
I don't know what c is sorry.
Hope that helps. x
-0.65
-3/8
2/4
5/16
I hope this is right, the negatives should go first because you are taking away, then positives
