Answer:
Length = 6 cm and width = 4 cm.
Step-by-step explanation:
Let the width be x, then the length is x + 2 cm and its area = x(x + 2).
The new width and length are x + 4 and x + 6, and the new area is
(x + 4)(x + 6).
So we have the equation:-
(x + 6)(x + 4) = x(x + 2) + 56
x^2 + 10x + 24 = x^2 + 2x + 56
10x - 2x = 56 - 24
8x = 32
x = 4 cm = width
and length = 4 + 2 = 6 cm
Answer:
35 degrees
Step-by-step explanation:
180 - 110 = 70 (TUW and UWT together)
70 / 2 = 35 (UWT)
Since the other part is congruent, we can assume it is also 35.
26 possible letters
assuming you can repeat them
26*26*26
no listed
ok, lets assume that you can't repeat them
that is 26 times 25 times 24 (because you used 1 each time)
that is 26!/23! (because 26*25*24*23!=26!)
answer is D (only if there is a factorial sign after the 23)
The mean is 27.5. I hope this helps :)
