Answer:
-4 and 4
Step-by-step explanation:
Have a good day.
Just replace x with whatever , and see if it works. If it works then it is a solution; otherwise it's not.
1^2 is not 2
(1/2)^2 isn't 2 either...
and so on
Let the length of rectangle be L and the width of rectangle be W.
Since length exceeds the width by 25 inches, length will be
L = W + 25
Now the perimeter, P, is given by
P = 2(L + W)
Substituting L = W + 25 in the above equation,
P = 2(W + 25 + W)
P = 2(2W + 25)
P = 4W + 50
But P = 86 inches
P = 4W + 50 = 86
4W = 86 - 50 = 36
W = 36/4 = 9
Hence, width W = 9 inches.
Length L = W + 25 = 9 + 25 = 34 inches.
Answer:
Step-by-step explanation:
Lets start with 13
-2(13 + 3) = -4(13) + 20
-32 = -52 + 20
-32 = -32
x = 1 basically
now 19
-2(19 + 3) = -4(19) +20
-44 = -76 + 20
-44 = -56
so divide those
-2(31 + 3) = -4(31) + 20
-68 = -124 + 20
-68 = -104
divide them
-2(37 + 3) = -4(37) + 20
-80 = -148 + 20
-80 = -128
22. P(n > 3) = P(4)+P(5) = (4+5)/30 = 9/30 = 3/10
23. The game isn't fair because there as many even numbers as there are odd numbers on a die. You get double the points he gets at the same chance!
