The perimeter of an equilateral triangle is 63 in.
the length of each side is (4x+3), find the value of plz

Because it is an equilateral triangle, all three sides are the same length.  Because of this, you need to divide 63/3 to find out the length of one side.  63/3=21.  So this tells us that 4x+3=21.  Now that we have the equation, we need to solve for x. To do this, subtract the 3 on both sides to get 4x alone.  21-3=18.  So now we know that 4x=18.  Now divide 4 on each side to get x alone.  X= 18/4, which simplifies to 9/2.  In decimal form, x=4.5.

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
