If a pentagon is regular, then all of the sides are the same length. This means that

5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5

So, if x=5, the lengths of the sides evaluate to

5x-4 = 25-4=21,\quad 2x+11=10+11=21

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.

5/8 ≠ (3/4 + 1/16) because 5/8 < 3/4 EXPLAIN THIS PROBLEM AND WHAT IT MEANS
balu736 [363]
5/8 = 3/4+1/16 is false because, the final values compared on each side of equation is not the same

A street has parallel curbs 40 feet apart. A crosswalk bounded by two parallel stripes crosses the street at an angle. The lengt
andreev551 [17]

Answer:

The distance, in feet, between the strip = 12 feet.

Step-by-step explanation:

From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where

CD/AB = CE/AE

CD = 40

CE = 50

AE = 15

Let AB = x

50x = 15 × 40

X = 12

 The distance, in feet, between the strip is therefore 12 feet
