Give me brainliest please
W=x
L=2x-4
Perimeter=88
Perimeter=2(l+w)
88=2(2x-4+x)
88=4x-8+2x
88+8=4x+2x
96=6x
96/6=x
16=x(width)
Answer:
First, you combine like terms.
Then, you divide both sides of the equation by the same term.
Next, you simplify.
Lastly, you have your solution, which is x= 18

In the same circle, or in congruent circles, two chords are congruent if and only if they are equidistant<span> from the center. States that the measure of an inscribed angle is one half the measure of its intercepted arc. States that if two inscribed angles of a circle intercept the same arc, then the angles are congruent.

Answer:
1) Is more representative
Step-by-step explanation:
The problem with his selection is that maybe there are few students participating in certain sport and those students maybe do quite more excercise than the rest (or quite less). This will modify the results because the sample he selected is biased. This problem wont be solved by method 3 or 4, because he is still selecting students that may modify heavily the results with a high probability
This problem will also appear if he choose a sample by class. Maybe, in a class there are quite few students, and selecting from class will make those students appear quite more often than, lets say, a 7th grade student selected at random, therefore the selection is biased in this case as well.
If he has a list with all seventh grade students, each student is equallly likely to be selected and as a consequence, the the results wont be biased. Approach 1 is the best one.
