a non-regular Pentagon has 3 sides that are the same length. the 4th side is 6 inches longer than the length shared by 3 of the

Answer:

15 inches

Step-by-step explanation:

Okay, so we know a pentagon has 5 sides total. We also know that 3 of the sides are the same length, so let's assume those sides are n length.

n + n + n + _ + _ = 4ft 11in

The fourth side is an inch less than n.

n + n + n + (n - 1inch) + _ = 4ft 11in

The last side is 6inches more than n.

n + n + n + (n - 1inch) + 9n + 6inches) = 4ft 11in

Now that we have out equation, lets convert the 4ft 11in into just inches. 4ft = 4 x 12 inches (48 inches). Then add the 11inches and you get 59.

Now our equation is in terms of inches,

we can combine the 3 ns to 3n.

3n + (n-1) + (n +6) + 59

Then we combine all the ns and get 6n -1 +6 =59

Simplify to 6n +5 =59

then to 6n = 54

Then to n = 9.

Since we are looking for the longest side, you have to substitute n in for the side that would have the longest measure, n + 6.

9 + 6 = 15.

15 inches is your answer.

liubo4ka [24]

Answer:

a) AUB = {2,3,4,6,7}

b) $A\cap B=\{4,7\}$

c) $C'=\{1,2,4,6\}$

d) $C-B=\{3,5,8,9\}$

e) $(B\cup C)'=\{1,2\}$

Step-by-step explanation:

Consider the provided set.

A = {2,3,4,7}, B = {4,6,7}, C = {3,5,7,8,9}

Where A, B, and universe of discourse $U=\{x\in Z|1\leq x\leq 9\}$

So $U=\{1,2,3,4,5,6,7,8,9\}$

Part (A) Calculate AUB.

AUB represents the elements which are in A or in B or in both.

Therefore, AUB = {2,3,4,6,7}

Part (B) Find A n B

$A\cap B$ represent the elements which are in both the set A and B.

Therefore, $A\cap B=\{4,7\}$

Part (C) Find C'

$C'$ represent the elements that are not in C.

So the set C' contains all the element of set U except 3,5,7,8,9

Therefore, $C'=\{1,2,4,6\}$

Part (D) Find C-B

$C-B$ represent the elements of C which are not the elements of B.

So the set C-B contains all the element of set C except 7

Therefore, $C-B=\{3,5,8,9\}$

Part (E) Find (BUC)'

$(B\cup C)'$ represent all the elements of U which are not in B or in C or in both.

$B\cup C=\{3,4,5,6,7,8,9\}$

$(B\cup C)'=U-B\cup C=\{1,2\}$

Therefore, $(B\cup C)'=\{1,2\}$
