The length of a side of a square is given by the expression 3x - 1 and its perimeter is 20 cm. Write and solve an equation to find the value of x. Which of the following
have both the correct equation and side length of the square?
A. 4(3x - 1) = 20; side length = 4.25 cm
B. (4 x 3x) - (4 x 1) = 20; side length = 5 cm
C. 12x - 1 = 20; side length = 1.75 cm
D. 4(3x - 1) = 20; side length = 2 cm

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

i think it is 70

step-by-step explanation:

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

the answer to this is 4340

hope this if needed hmu
